"It is very possible that Google is creating their own branded digital television DVR / satellite service.
A DVR that lets you "log In" with your Google Account before you begin your television watching would allow Google to serve up relevant ads based on the program you are watching, your search history, the type of emails you have received in the past 24 hours (excluding spam hopefully), or anything else Google can track. Imagine the possibilities."
