Abstract
Television programming may be annotated with metadata and the metadata may be shared among subscribers. A set-top box may receive, from a server, metadata relating to a television program, the metadata having been created by users of other set-top boxes and at least some elements of the metadata including information describing portions of the television program to which the metadata is relevant. The set-top box may present the metadata during portions of the television program at which the metadata is relevant.
