LOS ANGELES  Google is experimenting with a new method of distributing original material on the Web, and some Hollywood film financiers are betting millions that the company will succeed.

In September, Seth MacFarlane, creator of “Family Guy” on television, will unveil a carefully guarded new project called “Seth MacFarlane’s Cavalcade of Cartoon Comedy.” Unlike “Family Guy,” which is broadcast on Fox, this animation series will appear exclusively on the Internet.

The innovative part involves the distribution plan. 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. The content will also be distributed via YouTube.

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.
