What is it? We don't really know yet, although its aim is to marry the Web and the television set. It's clearly Google's effort to wrest a large piece of the television advertising pie.
Here's what it seems to be: A marriage of platforms to permit universal search of television and Internet video, an intiative to make television a development tool, and an olive branch to Flash (arguably the best delivery of Web video to the screen, and most recently shunned by Apple, who will be Google TV's principal competitor).
Sony will unveil it in an HDTV later this year and Logitech will deliver the search box.
