The estimated $74 billion dollar a year ad market is a piece of the pie that Google wants to devour. According to CEO Eric Schmidt, the company wants to creat target ads to TV watchers so they won’t be wasting their time watching ads for products they’ll never be interested in (think of the college students who have to endure all the Depends ads on The Price Is Right). I have no idea how Google plans on narrowing a target market such as this. It remains unclear. Online, monitoring demographics is obviously much easier and part to Google’s success with AdWords. They could target ads based on the time and channel your watching in conjunction with your web browsing. It might be some other way. We’ll have to play the waiting game and keep everyone up to date on the matter.
