Here is a nice summary article of the speculation surrounding Google’s tentative foray into TV.
Google wants in on the TV business. How badly? It’s not quite clear yet. For a year now, the search giant has been working on a new service that incorporates conventional TV and Internet content, reports The Wall Street Journal. It would run on TV set-top boxes that are connected to the Internet and use Google software. Users will be able to search through and create lineups of content from TV and web video services like YouTube.
