Advances in Online Advertising

In a news article titled "Microsoft hopes to cash in with click-on ads", it is discussed:

Microsoft is hoping to expand on the concept with a new technology that allows viewers to click on cars, clothing or other products that appear in online movies or TV shows. For example, viewers of "Sex and the City" could click on Carrie Bradshaw's designer shoes or Kamali sweaters as she walks down a New York street and immediately be transported to advertisements for those products.
... online advertising, currently a $14.6 billion market, is the latest area where it is focusing attention. "We are determined to establish Microsoft as the top leader in this space," said adCenter general manager Tarek Najm.
Spending on online advertising in this country is expected to nearly double in the next five years to $26 billion -- or 8 percent of the entire advertising market, according to Forrester Research.

There are possible thoughts that come to my mind. Some extrapolations of the current trend of online-ad-economy; perfected by Google-AdSense.

AdSense + Cable TV: Cable as an online media delivery service is currently delivered with advertisements. Very soon cable can be made free. Set-top boxes will allow controlled advertisements to be delivered on televisions. The amount of advertisements delivered will determine the cable-rate. In fact set-top boxes can in some cases be integrated with AdSense to deliver personalized-advertisements based on user's channel-preferences. There is a lot that can be done here. This will particularly become interesting with IPTV. In fact the settop boxes can do time slicing of video broadcasts (over IP), and embed ‘tagged advertisements’ on TV.
