APT from Yahoo (formerly Project AMP and Apex) is an online advertising management platform from Yahoo. Announced on 7 April 2008, the service seeks to make selling and purchasing ads easier through a common interface. The platform will begin to be introduced in quarter 3 of 2008, although members of the Newspaper Consortium organized by Yahoo were allowed to preview AMP early. The service will sell online advertising for search, display, local, mobile, and video mediums.
