I think that Google TV is incorporated directly into the television. SONY is coming out with a new line of “Internet TVs” which will allow you to watch tv and surf the web while sitting in your easy chair, using your remote control. Since Google TV allows you to choose a network show that is available on the internet, the major networks are afraid this would destroy their 60 year-old advertising paradigm. That is, a show was broadcast at a specific time, and people watched it, while being forced to view the commercials which sponsor the show.
By blocking the availability of doing this directly on your tv, the networks are trying to hold back the inevitable. The article states that people can get around the block by hooking up their computer, which has the content, to their television set.
