Microsoft's MSN division is looking for testers to try out its new adCenter product in the United States through a recently launched pilot program. Yusuf Mehdi, senior vice president of MSN, asked employees last week to invite businesses who might be interested in the service.

MSN adCenter was moved out of testing in France and Singapore last month, with Microsoft saying it had received positive feedback on the service.

What makes adCenter different is the fact that advertisers will be able to target their campaigns towards a certain demographic, Microsoft says. MSN will use generic data collected from its Web properties in order to ensure ads get in front of the consumers that advertisers are looking for.
