Abstract: Systems and methods for providing targeted content in streaming content online that takes into account content, including advertising content, delivered in a corresponding linear broadcast over a defined period of time (e.g., one day, one week). A broadcast content management system is provided that generates a multicast log that corresponds to a broadcast log, and sends the multicast log to a streaming content management system. The streaming content management system utilizes information in the multicast log to select advertisement content to be served to media player systems (e.g., video players).
