Description

The 20th Century was the century of broadcasting. It started with radio, then cinemas and finally TV. All one-way broadcast mediums. They all have one restriction. They are based on a model of scarcity, i.e. program directors have to choose the program for you, since there are only finite number of channels and screens.

Television has not really changed very dramatically for many years. The only major upgrade was adding color. However we are now seeing another change: Digital TV. Changing TV to digital has already had impact. Digital means better picture and sound, but also some changes in distribution. Also, with digital TV, software starts to play a major role and the Internet will become a possibility as distribution mechanism. This will cause disruption In this lecture we look at home entertainment from the days of talking machines to our times of Internet TV, Interactive TV and IPTV.

In this lecture we look at how content viewing is changing and why the TV industry getting disrupted.
