  |  March 27, 2009   |  Comments

The top 50 ad networks in February by unique visitor.

The top spots in comScore's AdFocus rankings, which tracks ad networks and Web properties, showed little movement from January. Platform-A captured 173 million unique visitors; Yahoo saw 163 million uniques; and ValueClick served 157 million uniques. Specific Media came up a spot (143 million uniques), taking a space previously occupied by Yahoo sites. Google came up two pegs (141 million uniques), displacing Tribal Fusion and Traffic Marketplace.

Microsoft consolidated its ad network properties under Microsoft Media Network U.S., dropping the DRIVEpm identity. In February It held at 123 million unique visitors. In January DRIVEpm had 126 million uniques. In all, the number of unique visitors to each network, and percent reach to all properties, tended to be smaller than in January.
