LOS ANGELES (Hollywood Reporter) - Google has enlisted Viacom's MTV Networks in an ambitious expansion of the Internet giant's advertising network and video portal, the companies said Sunday.

The deal calls for Google to begin testing at the end of the month the insertion of video into Google's targeted advertising system, AdSense, from hit Viacom-owned series like Nickelodeon's "SpongeBob SquarePants."

If the arrangement works, Google could allow any number of content companies to utilize the service, splitting ad revenue between them as well as the Web sites chosen to carry the clips, which are 2-4 minutes in length.
