NEW YORK (AP) - Microsoft Corp.'s video game advertising unit, Massive Inc., has signed deals with "Guitar Hero" and "World of Warcraft" publisher Activision Blizzard Inc. to provide ads for 18 of its titles and for Battle.net, its online game service.

Financial terms were not disclosed.

Massive said Wednesday it will deliver dynamic ads - which means the ads change over time and can be targeted based on a gamer's location, for example - to Xbox 360 and PC games including "Guitar Hero: World Tour" and "James Bond: Quantum of Solace."

Massive has already worked with Activision to create ads in previous games, including an earlier version of "Guitar Hero."

Massive, which brokers all ads for Microsoft's Xbox 360 gaming console, will also be the exclusive advertising service provider for Blizzard' Web sites and for Battle.net in the U.S., Canada, Europe, South Korea and Australia.

Gamers use Battle.net to play "World of "Warcraft," ''StarCraft," and other games together. "Warcraft" has more than 11 million subscribers worldwide.
