At 9:14pm on November 22, 1987, sportscaster Dan Roan was doing the Bears highlights on Chicago’s WGN-TV when the station’s signal was hijacked. Someone wearning a rubber Max Headroom mask appeared, silently, on TV screens around the city. A few hours later, Headroom popped up again on another channel, this time for longer and with audio. Despite FBI and FCC investigations, the case remains unsolved.
