Abstract: Promotions may be targeted to one or more device groups. A promotion/device group set relation is maintained for each promotion indicating the device groups to which each promotion should be sent. A device group corresponds to a statistically categorized group of end node devices (e.g. set top boxes) based on demographics or viewership history. A device group may be further subcategorized to include one or more transmission groups corresponding to the physical characteristics of the end node devices (e.g. hardware, memory capacity). A promotion server creates a package containing the promotion for each transmission group of the device group. If a package for a particular transmission group is already created and has sufficient available space, the promotion is simply added to the package. Therefore, a package created for a transmission group may hold promotions intended for different device groups even though not all of the promotions are targeted for the same devices.
