During an online event, a spectator process monitors a state of the event, updating a spectator model, so that spectator data streams can be generated and provided to spectators. The spectator data streams can be formatted and provided with content appropriate for use by different types of spectator devices used by the spectators. The spectator process can also automatically generate virtual commentary appropriate for the action occurring in the event for inclusion in the spectator data streams. A media server receives the rendered data streams and distributes them to the electronic devices being used by the spectators. The distribution can be delayed to avoid a spectator conveying information to a participant that would provide an unfair advantage. Executable code can be included in the spectator data stream to provide additional functionality and facilitate interaction between the spectators, and to enable a spectator to also "play" the game.
