Abstract: In order to coordinate an interactive computer game with a television broadcast, a central control establishes a large virtual environment in which viewers participate with characters either controlled or designed by them. Each user can directly control or influence characters within a “active region” which encompasses part of the virtual environment that is much less than the total environment. The broadcast portion of the system also has an active region, at least a portion of which is shown on a broadcast television show. The locations of the active regions are controlled by the central control. In accordance with one embodiment, the central control moves the active regions of selected users so that these active regions coincide or overlap the broadcast active region. The selected users are then allowed to control characters that appear on the broadcast television show.
