Google to Start Distributing Content via AdSense – NYTimes.com
“Google will syndicate the program using its AdSense advertising system to thousands of Web sites that are predetermined to be gathering spots for Mr. MacFarlane’s target audience, typically young men. Instead of placing a static ad on a Web page, Google will place a “Cavalcade” video clip.
Advertising will be incorporated into the clips in varying ways. In some cases, there will be “preroll” ads, which ask viewers to sit through a TV-style commercial before getting to the video. Some advertisers may opt for a banner to be placed at the bottom of the video clip or a simple “brought to you by” note at the beginning.”
