Tape and New Video Storage
Television has always had some capacity to record images and sound for later playback. Very early on film was the best available method to achieve recording and playback of material. However it was quickly identified that there needs to be some other sort of recording medium more suited to a television environment. In the 1950's magnetic tapes began to be used to record and playback program material, Ampex demonstrated the first viable VTR in 1956. Video tape technology continued to develop and in 1986 Sony introduced the first commercial digital tape machine using. In 1995 the KOLD 13 became the first television station to use a networked digital server to broadcast program content. Since then digital technology used to send images and sound to the consumer has become prevalent in all parts of television production.

Tape technologies are linear. They have to be seen in sequence and only the images at one point if the tape at a time can be seen. In the past this technology was adequate as editing was linear and playback was linear. For each playback and recording line there had to be a separate machine. This meant the operation of these machine could become very complex and for large productions many VTR's were needed to meet the playback, slow motion and recording needs.
With the advent of digital technologies the encoding of the tapes changed but apart from advances to the accuracy of the time-code the operation of these machines was virtually the same. This can be seen when using a DVCam machine and a VHS machine.
With the advent of Non-lenear video editing in the 70's people began to see the benefits of this new idea in editing. It also lead to a revolution in the way video could be stored that today is leading to developments in the broadcast market like the P2 technology from Panasonic. This revolution has also effected consumers with the explosion of TiVo in America meaning the viewer can record and playback program material as they wish and record and playback at the same time. However I don't think that such developments had the major effect that so many people have expected on the television market.

I think that advances relating to the internet will be the things that radically change the television market from the idea of watching what you are given that had been prevalent from the advent of television. Apple who revolutionized the sale of music has announced the iTunes music store will now sell television shows that can be downloaded and watched on the new iPod. Television stations will need to become internet content providers with the playback not coming from VTR machines but hard drives through the internet. In the next few years people will stop buying VCR's and DVD players but instead the home computer will become the television access point with a watch what you want attitude.
