BOOKING AND MANAGEMENT OF INVENTORY ATOMS IN CONTENT DELIVERY SYSTEMS

Systems and methods for managing electronic content from multiple content providers in a dynamic environment are provided. In operation, an advertiser can plan and book an electronic advertisement campaign by providing a campaign request specifying a requested inventory slot of atoms in an inventory space and other associated data. Thereafter, a proposed campaign can be generated based on an estimated availability of the atoms and any performance criteria specified by the advertiser. Once the proposed campaign is accepted and booked, the proposed campaign can be managed along with other active campaigns. These active campaigns can be managed based on a relative priority of the campaigns and an estimated availability for the atoms in the inventory space.
