Yahoo has reached an agreement to acquire Flurry, a mobile analytics company, as part of a push to grow its advertising revenue within its mobile products. Flurry provides tools that help developers and publishers learn more about who's using their apps in order to better target them with ads. The information, including gender, age and location, helps Flurry play digital matchmaker between publishers and advertisers. The technology can be used to place banner, full-screen and video ads.
