Sites that specialize in TV listings are going to be hot. CNET’s new one is just an example of how companies will use a listings grid as a platform to enable consumers to share great programming finds (everyone has an opinion) as well as perform DVR functions right from their PC. Check out MeeVee as another one these Web-based TV platforms. Mike and I have written about this trend, and it’s going to be huge and a key part not only of the development of IPTV/TV over the Web-type programming but also furthering the cause of viral sharing.
