Apparently Google is working on something that to me sounds a little freaky. Through a microphone in the room, a computer could listen to what’s on the television, and identify what the person is watching by taking a small audio snippet. That info can be fed back to Google to feed contextual advertisements back to the home viewer, or just spy on what kind of trashy reality shows you really enjoy.

Not sure what the benefit is, but if Google is working on knowing everything, then this will probably be part of it.
