A system and method are provided for creating social networks, such as text, video, or audio chat sessions, around recorded media. More specifically, a social network server operates to logically divide the recorded media into a number of time slices, which may be thought of as sliding time windows. When a user within a time slice desires to join a social network during playback of the recorded media, the social network server operates to either add the user to a pre-existing social network associated with the time slice or establish a new social network between the user and additional users within the time slice. As a result, the user may have meaningful social interactions with other users that are at similar points during playback of the recorded media.
