Yahoo! Go for TV is a downloadable video recording software that works with your TV tuner card and creates a Media Center-alike experience on almost any PC. It came out a few months ago, but now they’ve added Flickr integration, picture-in-picture functionality, movie recommendations, and local network music streaming.
The service is obviously free and probably one of the few ideas in this whole Web 2.0/post-content/advertorial world. Essentially, this gives Yahoo! a captive audience – unfortunately only folks with TV tuners really need apply because the rest of the functionality is a bit underwhelming – and puts Microsoft in the awkward position of having to make a good Media Center product.
