Blown Film Extrusion Introduction

Blown Film Extrusion Introduction
Blown film extrusion is a technology that is the most common method to make plastic films, especially for the packaging industry. The process involves extruding a tube of molten polymer through a die and inflating to several times its initial diameter to form a thin film bubble. This bubble is then collapsed and used as a lay-flat film or can be made into bags. Usually polyethylene is used with this process, and other materials can be used as blends with these polymers. A diagram of a polyethylene chain is shown in Figure 1 to the right.
Background Theory on Polymers

In the cooling step of blown film extrusion, the amorphous, transparent melt crystallizes to form a translucent, hazy, or opaque film. The point where opacity begins in the bubble is known as the frost line. 
Fig 1: Model of polytheylene chain frompolyethylene Wikipedia article.The frost line height is controlled by several parameters: the air flow, film speed, and temperature difference between the film and the surroundings. Properties of the film, such as tensile strength, flexural strength, toughness, and optical properties, drastically change depending on the orientation of the molecules. As the transverse or hoop direction properties increase, the machine or longitudinal direction properties decrease. For instance, if all the molecules were aligned in the machine direction, it would be easy to tear the film in that direction, and very difficult in the transverse direction.

The Film Blowing machine Process

Fig 2: Schematic of set-up from User:J.Chiang.

Typically, blown film extrusion is carried out vertically upwards, however horizontal and downward extrusion processes are now becoming more common. Figure 2 shows a schematic of the set-up for blown film extrusion. This procedure consists of four main steps: The polymer material starts in a pellet form, which are successively compacted and melted to form a continuous, viscous liquid. This molten plastic is then forced, or extruded, through an annular die. Air is injected through a hole in the center of the die, and the pressure causes the extruded melt to expand into a bubble. The air entering the bubble replaces air leaving it, so that even and constant pressure is maintained to ensure uniform thickness of the film. The bubble is pulled continually upwards from the die and a cooling ring blows air onto the film. The film can also be cooled from the inside using internal bubble cooling. This reduces the temperature inside the bubble, while maintaining the bubble diameter. After solidification at the frost line, the film moves into a set of nip rollers which collapse the bubble and flatten it into two flat film layers. The puller rolls pull the film onto windup rollers. The film passes through idler rolls during this process to ensure that there is uniform tension in the film. Between the nip rollers and the windup rollers, the film may pass through a treatment centre, depending on the application. During this stage, the film may be slit to form one or two films, or surface treated. Advantages Blown film generally has a better balance of mechanical properties than cast or extruded films because it is drawn in both the transverse and machine directions. Mechanical properties of the thin film include tensile and flexural strength, and toughness. The nearly uniform properties in both directions allow for maximum toughness in the film.
Blown film extrusion can be used to make one large film, two smaller ones, or tubes that can be made into bags. Also, one die can make many different widths and sizes without significant trimming. This high level of flexibility in the process leads to less scrap material and higher productivity. Blown films also require lower melting temperatures than cast extrusion. Measured at the die opening, the temperature of cast film is about 220 C, where as the temperature of blown film is about 135 C. Furthermore, the cost of the equipment is approximately 50% of a cast line.

Blown Film Extrusion Disadvantages Blown film has a less effective cooling process than flat film. Flat film cooling is done by means of chill rolls or water, which have significantly higher specific heat capacities than the air that is used in the blown film cooling process. The higher specific heat capacity allows the substance to absorb more heat with less change in the substance temperature. Compared to cast film, blown film has a more complicated and less accurate method to control film thickness; cast film has a thickness variation of 1 to 2% versus the 3 to 4% for blown film. The resins used for casting typically have a lower melt flow index, which is the amount of polymer that can be forced through a standard die in 10 minutes according to a standard procedure. The melt flow index for cast film is about 5.0 g/10 min where as for blown film it is about 1.0 g/10 min. Consequently, the production rates for cast film are higher: cast film lines can reach production rates of up to 300m/min where as blown film lines are usually less than half this value. And finally, cast film has better optical properties, including transparency, haze, and gloss.

Common Problems Air entrapment between film layers and rollers – this may cause film scratching or wrinkling, or processing problems when winding up the film due to reduced friction. Possible solutions to this is using a vacuum to remove entrapped air or by using winding rolls with a diamond shaped groove in the rubber cover to increase surface area and decrease amount of entrapped air in the film. Large output fluctuations from the die – this causes thickness variations, and can be prevented by keeping the extruder clean and by using more consistently shaped pellets in the extruder. Melt fractures – these appear as roughness or wavy lines on the film surface, and can be eliminated by lowering the viscosity of the polymer melt. This can be done by increasing the melting temperature or by adding an internal lubricant to the material composition. Thickness variations in the film – this can be avoided by centering the die in the extrusion line before every run, adjusting the air speed of the cooling system, or by using heated die lips. Die lines on the surface of the film – this defect reduces the aesthetic appeal of the film, reduces optical properties, and weakens mechanical properties such as tear strength. This can usually be avoided by routinely cleaning the inner surfaces of the die and by refinishing scratched or roughened flow surfaces. Gels – these defects are small, hard globules encapsulated in the film or stuck on the film surface and reduce the aesthetic appeal of the film and cause stress concentration points which may result in premature failure. These are caused by overheating to the point of polymer degradation in the die, and can therefore be avoided by cleaning the inner surfaces of the die on a regular basis. Optimization of the Process Coextrusion One way to improve the line efficiency of blown film extrusion is to implement coextrusion. This is the process of extruding two or more materials simultaneously through a single die. The orifices in the die are arranged such that the layers merge together before cooling. This process saves time because it extrudes two or more layers at the same time, and it provides a method with fewer steps to produce multilayer films. The production rate for a coextruded multilayer film of three layers is about 65m/min, and the production rate for a single layer of blown film is about 130m/min. Thus, in order to produce 10 000m of a three layer multilayer film, it would take almost 4 hours using a single layer blown film process, and only 2 and a half hours using the coextrusion process. Furthermore, the film produced from the single layer process would require an extra step to glue the layers together using some sort of adhesive. Coextrusion is the least expensive means of producing layered films and the coextrusion system is capable of quick changeovers to minimize production line down time.

Minimizing the Melt Temperature
The efficiency of blown film extrusion can be improved by minimizing the temperature of the polymer melt. Reduction of the melt temperature causes the melt to require less heating in the extruder. Normal extrusion conditions have a melting temperature at about 190 C despite the fact that the temperature of the melt only needs to be about 135 C. However, it is not always practical to decrease the melting temperature by that much. By decreasing the melt temperature 2 to 20 C, the motor load can be decreased by about 1 to 10%. Furthermore, reduction of the melt temperature causes less need for cooling, so there is a reduced use of the cooling system. Moreover, removing heat from the bubble is usually the rate-limiting factor in this extrusion process, so by having less heat in the polymer to remove, the rate of the process can be increased, thus yielding higher productivity. A way to maintain the melt temperature at a minimum is to choose an extruder that is matched to the specific processing conditions, such as the material of the melt, pressure, and throughput.

Heated Extrusion Die Lips
Typically, solutions to melt fractures involve decreasing the output or increasing the melt temperature to decrease the shear stress in the extruder. Both of these methods are not ideal because they both reduce the efficiency of the blown film line. Heated extrusion die lips can solve this problem. This targeted heating method allows for film extruders to be run at higher production rates with narrower die gaps while eliminating melt fractures. Direct heat is applied to the surface of the polymer melt as it exits the die so that viscosity is reduced. Therefore, melt fractures, which are caused when trying to extrude too much of the polymer at one time, will no longer act as a limiting factor to increasing the production rate. Furthermore, heated die lips use less energy than increasing the melting temperature because only the surface of the melt is heated and not the bulk of the liquid. Another benefit of using heated die lips is that thickness variations can be controlled by adding heat to certain areas along the die circumference to make the film at that position thinner. This would ensure that no excess material is used.
Determine how much energy each of these processes can save per given volume of material.

An Efficient ApprAn Efficient Approach to Reputation Management in Cyberspaceoach to Reputation Management in Cyberspace

You cannot resolve conditions that that you don’t know are present, and this is a fact regarding a vast assortment of spectrums. No matter if you might be a mommy accountable for safeguarding your young ones, that happen to be currently being swayed by things of which you might be uninformed, or even a car owner that is fully unaware their vehicle is getting ready to run out of oil as the instrument data panel that’s on the dashboard isn’t functioning. This is equally true of your business owner whose particular firm is now being maligned all through the Internet by a smear plan that was started by a rivaling enterprise across the city, an activity of which the business operator is actually unmindful since he doesn’t take part in social networking. Or perhaps he does, but not to the amount necessary to keep mindful.

The fact is, no business proprietor has the ability to be on the Internet and engaging in social media to the amount required in order to continually be up to date with remarks becoming made and embraced on Facebook, Twitter, LinkedIn, and other social networking sites. In the event that he or she put in very much time trolling the social website communities, they may not be accessible to make schedules, obtain products, welcome clients or monitor workers. It really is of remarkable value, nevertheless, to generally make the effort to try and keep abreast of exactly what will be transpiring where one’s company is concerned, online. There are several techniques this can be achieved.

One, a brand managing system, such as chatmeter (chatmeter.com) can be used. Two, a position can be made for an member of staff who does little other than work social websites, both to reply to comments plus problems, and also, to help deliberately advertise the business’s brand. Of these two alternatives, some sort of merged method is likely to be the most effective. Chatmeter is definitely an good tool. Usually, chatmeter costs much less than the usual devoted member of staff while being even more thorough. After chatmeter has decided the use of written content about the company, plus supplied an alert, at that time an employee’s attempts can end up being put to operate, or maybe the owner/manager alone may react to inquiries, comments and also complaints on the Internet. The nice thing about this strategy could it be won’t waste resources, but alternatively, utilizes them more effectively.

Surviving the Threat – How TV Learned to Love the Internet

[ad_1]

When it comes to “old”   media ,  TV  seems to be the one form of traditional media that has learned how to utilize the net to its advantage. The internet is still a content threat, but the TV world, unlike the worlds of music, film and publishing seems to have more quickly understood the pitfalls and opportunities. Instead of pulling up the drawbridge and preparing for battle, TV joined in and utilized the internet.

Companies that make their living selling content are reeling. Newspapers have been closing at a record rate. The music business is reeling like never before. ITunes has helped reset the playing field, but it’s nothing like it was before. Book publishing has been hit, particularly the brick and mortar bookstores and for the film industry it could just be a matter of time, before the ability to download free content (legal or otherwise) will make a true dent in their profits.

When it comes to “old”  media ,  TV  seems to be the one form of traditional media that has learned how to utilize the net to its advantage. Advertising took a huge hit last year, but the economy was also in the throws of the worst recession since the (strangely named) Great Depression. Just about everyone took a huge hit last year, not just TV ad revenues. But apart from basic economic ebbs and flows, TV seems to be the one form of media that has not only been able to weather the internet threat, but to utilize it.

To quote a recent article in The Economist: “In the final quarter of 2009 the average American spent almost 37 hours a week watching television. Earlier this year 116 million of them saw the Super Bowl-a record for a single program. Far from being cowed by the new  media ,  TV  is colonizing it.” The article goes on to explain how shows like “American Idol” and “Britain’s Got Talent” utilize the net to their advantage. Watchers are constantly messaging one another about such shows on email IM, Facebook or Twitter.

Plus, TV is a reactive media. It doesn’t require much from the viewer. You turn it on, put on the channel you want and there you are. Although many programs are available online, most viewers are not going to do the work it takes to find their programs through nontraditional outlets. The internet is still a content threat, but the TV world, unlike the worlds of music and publishing seems to have more quickly understood the possible pitfalls and opportunities. Instead of pulling up the drawbridge and preparing for battle, TV joined in creating sites such as Hulu a joint venture of ABC, Fox and NBC; an unlikely partnership, but a smart one.

Other content providers are beginning to understand that the way to fight the internet is not to fight it at all, but to blend with it and make it an extension of their brand and their information outlets, but the TV world is way ahead of the game

Media Influence – The Effects Media Has on Each of Us – Without Us Being Aware of That

[ad_1]

Many people do not realise how much media affects us in our daily lives. We are literally controlled by media: it determines the way we dress, what we eat and what lifestyle we pursue. Many people spend hours just flicking through channels till their bedtime.

Although we may not realise, it is media that makes us feel the way we feel, which is usually depressed, having no purpose in life and just feeling sad. The more you watch TV or listen to radio news, the more disasters you will hear, e.g. that someone was killed in your neighbourhood or that times are hard. Media forms the way we think and we let the media do this.

From my personal experience I can tell you that I have not watched TV for two years now. As soon as I stopped watching it, I instantly became happier. Instead of watching TV or flicking through newspapers I spent my time reading about how to acquire wealth, how to be healthy and positive. The absence of the influential media changed my life. I became a different person – I stopped gossiping, judging people, I became much more positive and happy. To tell you the truth, I did not have a bad day since I stopped being involved in the media.

But then many would argue that it is impossible to disengage from media as we would be not updated on current situation etc. But I would rather CHOOSE what I wish to be updated on by using on-line search engines, rather than just turn on the TV only to be bombarded by the depressing information.

Why do we always hear more negative than positive information on TV? Why do we feel sad, angry and insecure after watching news? Sometimes I think that society is kept in fear by such ways. Then common people are discouraged to achieve more, to start their own business because the media tells them that now the economic situation is disastrous and many businesses fail. I think it is ridiculous when people take everything that is told for granted.

The way many people live can be summed up in a few sentences: they work for someone else, they go home, eat, watch TV and sleep. Then on weekends they go shopping for cheap stuff to spend all their money in useless ways only to find themselves in debt after a few days of getting salaries. Then they go on vacation for a week or two once a year.

That is not life. That is a horrible loop they are stuck in. To break away from such life means to change habits. Change the habit of listening to media to doing something useful in that time. Reading is always good. Reading how to acquire wealth was my favourite pastime.

If yo do not like to read, buy educational tapes or DVDs, attend seminars. These are interactive and very useful ways to acquire knowledge and change your life. When you stop listening to the media, you will find yourself happier, healthier and wealthier. You will travel much more often, meet interesting people, maybe even start a new relationship. Things will change – I will guarantee you this. Get rid of this negative influence and you will change your life for good.

Do not hesitate to email me with your feedback on my articles! Thank you for taking time to read this post.

I Watch TV on My PC For All the Best Movies

[ad_1]

I am so happy I just discovered I can watch TV on my PC. Before television on my computer I was paying over $75 a month for cable. Canceling your cable service is a very pleasurable experience. The customer service representatives there sometimes say that getting tv on your PC isn’t possible. One only has to try the service for a minute to know this isn’t true.

There are several options out there. To get tv on your pc used to require additional equipment. This is no longer the case. If you have a PC and are online, then you are ready to go. All you need is a simply downloaded program. Some companies attempt to charge a monthly license fee for this software in an attempt to mimic the cable companies.

A few allow you to break the monthly payment cycle forever. Charging a one time fee only, you are perpetually able to receive satellite tv channels with no ongoing cost. Many think it sounds to good to be true. I admit I was one of them. However, seeing is believing. Not only does it work, but you would be astounded at the selection of programming.

Some programs offer up to 3000 channels. Yes, three thousand. That puts my old cable line up to shame. It is possible to receive channels from all over the globe. Watching live coverage from Rio one minute then Iraq the next is wild. It is as if a window has opened up to the world. Whether it be news, sports or movies the best of all countries becomes available right on your PC.

Friends who are rabid soccer fans are rushing to get this service now. Whatever the sport, many fans can not access their favorite games and team on regular cable television. Satellite TV on your computer allows for an incredible choice between events from all over the world. Never again will you utter that there is nothing good on to watch.

As I mentioned, the best part is that there is nothing left to pay after purchasing the initial software. Never. No ongoing monthly bills like all normal cable and satellite services entail. I read this software used to cost several hundred dollars. Some companies would charge comparable amounts to cable bills for its use each month. However, recently that has changed.

My timing was perfect because the most cutting edge package has now hit the market, and I can’t believe what a bargain it was. After confirming with the seller that it was 100% legal, the plunge was made. Download was as simple as downloading and installing any other software program.

Within minutes, I was able to watch TV on my PC. The best part is that home computers are now easily connected to televisions. Viewed this way, the amazing high def picture is fully experienced along with all sound effects. Nothing is missing except the bill. Added were several thousand channels. I wonder why anyone has cable anymore.

Media-Ocrity: Why Impartiality Is Not Their Concern

[ad_1]

The late Terence McKenna, the American ethnobotanist and mystic, once exclaimed, “We have to create culture, don’t watch TV, don’t read magazines, don’t even listen to NPR. Create your own roadshow. The nexus of space and time where you are now is the most immediate sector of your universe, and if you’re worrying about Michael Jackson or Bill Clinton or somebody else, then you are dis-empowered, you’re giving it all away to icons, icons which are maintained by an electronic media so that you want to dress like X or have lips like Y. This is shit-brained, this kind of thinking. That is all cultural diversion, and what is real is you and your friends and your associations, your highs, your orgasms, your hopes, your plans, your fears. And we are told ‘no’, we’re unimportant, we’re peripheral. ‘Get a degree, get a job, get a this, get a that.’ And then you’re a player, you don’t want to even play in that game. You want to reclaim your mind and get it out of the hands of the cultural engineers who want to turn you into a half-baked moron consuming all this trash that’s being manufactured out of the bones of a dying world.”

Indeed, the media has been responsible for propagating the widespread misinformation we see today. This insidious plot of social engineering, whether we acknowledge this or not, can be found in tailored TV, radio and newspapers, that are filled with celebrity tittle-tattle and government propaganda, (ISIS, Syria, et al.), essentially giving their recommendations on what to wear, who you should aspire to be, and what to believe. Most of it bile with endless fear-mongering and lacking any semblance of truth.

Impartiality is not their concern, and control and obedience is, and remains their sole aim as they continue to churn out half-truths and innuendos that line a popular political narrative that stick like barnacles on a whale, to nudge and cajole a susceptible viewing public to align with one commonly held point of view.

Most people are aware of this of course, however, as social conditioning is part of the fabric of our media culture this can go unnoticed, and is transferred as if by osmosis, and we are affected regardless, unless are concerted effort is made on our part not to react in the negative. The general populace can seem so burdened by the very act of daily living, they can feel almost powerless to mount a rebellion. However, a sea of change is afoot and those among the elite know this, and the movement is now gathering pace.

What we can do now is to resist this element of mind control by refusing to listen and to explore other sources of information to keep up to date and well-informed. Turning off the TV and radio in the first instance, and in so doing taking some of our power back. Effectively shutting the hatch on the rising tide of excrement that you may hear lapping against the shutter door, but just enough to prevent it seeping through. Expunged of government and media brainwashing tactics, we will hopefully develop a clearer mind and become instinctively aware of the many injustices around the world, and by refusing to accept the status quo, potentially enable everyone to live more empowered and fulfilling lives and finally usher in the long-awaited collapse of the controlling elite.

Fanning the Flames of “Media Created” Anxiety – A Break From Unnecessary Drama

[ad_1]

Tips for gaining control of your life…

The news media is more than a source for information and current events. It has become a “roller coaster ride” of drama and self-aggrandizement. We consumers of these presentations are swept up and our visceral anxiety responses are fanned into a frenzy. But why are swept up in this media blitz of emotion?

Since the dawning of the “Information Age” in the 1970’s, we have been steadily drawn into an escalating 24/7 need for worldwide news and the media has provided us with anxiety producing excitement from every corner of the world. Technology allows this instant communication and seems to encourage our “need to know” mentality. We “need to know” because we have a very primitive survival mechanism that stimulates our external focus on any threats, even perceived threats that may exist thousands of miles away, so our unconscious minds can protect us by preparing to fight or to flee from “danger.” When the Flight/Fight Response is triggered, our reactive, survival mechanisms take priority. We can react with “knee jerk” habitual patterns that are unique to our learned responses, but are born from the survival reaction. One major reaction that occurs for many people under threat is a reduced ability to creatively problem solve and communicate effectively. We react and often do not really think things through. When this occurs, mistakes can be made. Accidents can happen. People or projects can get hurt. Relationships can be harmed. Our world can suffer by becoming a victim to poor rational thought in cases of fear or media driven anxiety. It is an extra “heaping, helping” of annoying distractions that take us away from self-care, focus on priorities, and creative pursuits that promote productivity and well-being.

Just before 9/11/2001 our news media changed. Do you remember? About 3 months prior to the terrorist attacks on New York, Washington, DC, and Pennsylvania, the television news media upgraded their reporting to include, not just a “talking head” (reporter) giving us the “news” but also text messages flying by on the bottom of the screen, and often a graphic on the left of the “talking head.” Now we have to deal with 3 sources of information simultaneously. This multi-tasking creates added frenetic anxiety in coping with this increased input. Have humans evolved to keep pace with this new use of technology? When we are threatened, we have a response that NEEDS to know what is going on around us so that we can take action and survive any threat. We are often overwhelmed. We have learned to cope by becoming unconscious regarding this media craziness. The media fights to keep our attention. The media has evolved their approach to sensationalize their coverage, to yell at us even louder, with more graphic events that “demand” our attention. Even the weather news whips us with “STORM” coverage that makes weather events major news, even when it occurs hundreds of miles away!

To combat this media blitz on our senses we must do three things. First, we must become aware that we can become victims to sensationalism that may not necessarily be an immediate threat, and filter the news so that we can respond more appropriately. Secondly, as my friend Rodger Ruge suggests, we should consider a media “Fast,” where we reduce and limit the amount of media news that we subject ourselves to. For many of us, turning off the news, especially before bedtime, would be a very good option. The third necessary step is to practice self-care and strengthen our emotional foundations by eating better, avoiding caffeine, getting regular exercise, and practicing daily relaxation.

Awareness of the media frenzy can help protect us and our children from the “overwhelm.” Since the mid 1980’s, we have been deluged by new technologies that force us to react to news and information that is swirling around us. We have experienced: pagers, fax machines, cable TV with 500 channels, Cell phones, text messaging, e-mail, internet information, changes in media coverage of world “disasters,” “robo-calls” at dinner time, and huge expectations that we are plugged in 24/7 and can respond instantaneously even when we are driving our cars…. This is crazy making! Some people can handle this gracefully, in fact, some people can thrive in this environment. But most of us are just victims to our technology and can benefit from setting some limits on the ways that we use, and react to, our technologies… We need to evolve and to create survival strategies that meet our unique, individual requirements.

Please be smart and figure out how to “not become a VICTIM” to the media and our newest technologies!

When we see natural disasters on the TV, we think that we filter the visceral effects on our survival systems, but our unconscious often reacts to the possible threats that are perceive through our visual and auditory senses. When we witness “coverage” of war zones, murders, attacks, rapes, fires, or vehicular accidents, we may believe that this does not affect us at a “conscious level,” but we are still triggering the flight/fight response in some systems at an unconscious level. Have you ever noticed your heart race or your gut tighten when confronted by news or movies? Does your neck, jaw, or back react to accidents or disasters that you witness in person or on TV? Do thoughts of “media images” ever pop into your conscious mind as you try to sleep? We are bombarded by negative media attacks almost everyday.

Do media pundits ever whip you up with their “news coverage” or editorials so that anger or fear seem to rise to the surface of you or your loved ones? This can be emotionally and physically hard on our systems…. Be aware and do not get caught up in the media circus, if at all possible.

Final note. Many people are studying and applying the principles of the “Law of Attraction” believing that goal setting and positive attitudes toward achieving these goals is essential to success. World class competitive athletes have been using these “Sports Psychology” techniques in their training regimen for decades to achieve advantages in mental preparation in their events. When we get caught in the sensationalized, negative reporting by the various media we are sapped of our positive thoughts and energy. We lose our focus on attracting success and positive outcomes. In fact, we can be overwhelmed by negativity. This can strip you of your ability to problem solve in positive and creative ways. Negative thoughts can attract negative outcomes, mistakes, and ill health. Avoiding negativity (and negative thoughts) can be a path to better health and lead to positive outcomes. “Dwell in the Light” and when you feel overwhelmed, consider turning off the negative newscasts and immerse yourself in a book or audio program, or a video that will inspire you with positive; thoughts, actions, and emotions.

How MTV Got Started and How it Has Influenced Television Today

[ad_1]

For many young adults, they can never imagine life without computers, music video production and reality television. Many of these things got it’s start in the 1970’s or even later. This article will discuss the history of MTV, or the music television channel that has become a staple of cable television for many households with teens or young adults. Today’s youth are much more tuned into various types of media outlets using their computers or phones to see videos on Facebook, vimby preditor, Twitter and YouTube. It all started in 1977 with a small cable TV network that had a show called Sight On Sound in Columbus Ohio.

This show was a new concept as a music channel that featured concerts as well as music oriented TV programs. It was the first two way cable TV program where viewers could call in and vote for their favorite song or artist that was being shown on the program. This cable network also had other programs like a children’s show but the one that really became popular was the music channel. Viewers had never been able to see a concert or see a band interviewed on TV before unless they went to a concert themselves so it was a great new concept. With this increasing popularity, the network changed their format in 1981 to be called MTV-music television.

The original idea of MTV was to model it after the top 40 radio shows, putting on the best pop rock bands at the time. Instead of having a disc jockey like they did on the radio, they hired several young hip hosts to introduce the videos and called them VJ’s as in video jockeys. Some of these original VJ’s on MTV ended up being celebrities in their own right from the enormous amount of exposure that they got from being on MTV at the start.

Because music videos started out as just someone recording the band playing music, many film directors got involved and started creating a much more elaborate concept for the videos. They took a song and made almost a small movie type of clip that told the story of the song. This is how many of these film directors that went on to be quite famous got their first start, making music videos. With the increasing popularity of this channel and the new wave of music videos playing in the early 1980’s, the network created the MTV Music Video Awards in 1984. This was a way for the music industry to showcase some bands in a more hip and alternative way than the Grammy’s offered.

MTV soon started adding other types of shows on the channel like animated cartoons for the adolescent and young adult crowd, and they were the first ones to have a reality show creating the concept of the Real World where they had several young adults live together and have their lives filmed while adjusting to each other and a new city. MTV pioneered many of the popular shows that young adults continue to watch today.
