Providing a coordinated primary media stream with an aggregate supplemental media stream is disclosed. A request is received from an end user device associated with a user for supplemental media. Metadata and a broadcast time associated with a primary media stream transmitted to the end user device are determined. Based on the metadata and the broadcast time, first supplemental media from a first account of the user on a first platform and second supplemental media from a second account of the user on a second platform are determined. The first supplemental media and the second supplemental media are merged into an aggregate supplemental media stream. The aggregate supplemental media stream is streamed in synchronization with the primary media stream.
