Google to Become Ad Network?

Apparently, Google is moving more aggressively into the advertising business. They are starting a new text ad program, Google Content-Targeted Advertising, which will display ads on non-search related pages. This ad program, like those ads that Google now shows on its site, are not graphics or banner ads, but text ads with a colored background. They are free until March 12, but where they will be displayed after then remains to be seen. See also Google's FAQ for Content-Targeted Advertising.
