Abstract: Content streams are enhanced through management of spectator tracking and reward determinations via a central system between a streamer client device and spectator client devices. Spectators viewing a content stream of a title streamed over a network via a title rewards service from the client device executing the title are tracked along with their time spent viewing the stream. An indication of a reward received from the streamer client device causes the title rewards service to determine spectators meeting reward criteria and issues a multi-cast reward notice to qualified spectator client devices. Spectators authenticate with the title rewards service as players of titles to redeem rewards that are provided by the titles at their client devices. Spectators of unintegrated titles are also tracked for later rewards when such titles are integrated into the title rewards service.
