On the night of November 22, 1987, Chicago viewers watching WGN’s evening news saw the sports report give way to a man in a Max Headroom mask. The picture moved and the soundtrack buzzed. Within about 25 seconds the station had its broadcast back. Two hours later the mask appeared on a different channel. This time the figure had a voice.
WGN and WTTW carried two separate unauthorized transmissions that night. What appeared on screen survives in recordings. Who made them and exactly how the signals reached the transmitters remain unresolved.

Creepy Broadcast and Video Mysteries — The Signals, Channels, and Uploads That Terrified the InternetA normal night in Chicago
WGN was carrying its nine o’clock news. A viewer tuning to the station expected the same broadcast being assembled in its studio. What the incident exposed was the distance between those two places, a distance the station’s own programme had to cross before reaching the television set.
Two stations would become targets:
- WGN-TV Channel 9, known for local news and Chicago sports coverage.
- WTTW Channel 11, Chicago’s PBS station and home to educational programming and shows like Doctor Who.
WGN sports anchor Dan Roan was on air when his segment was interrupted. The second intrusion happened later in the evening, during WTTW’s broadcast of the Doctor Who story Horror of Fang Rock.
The first intrusion
During the sports report, the station’s picture was replaced by a figure swaying in front of a ridged backdrop. The mask imitated Max Headroom, a familiar fictional television personality. In the WGN interruption the audience heard buzzing, without intelligible speech. The station restored its signal and Roan returned to viewers who had seen a picture he had not put on the air.
The second attack was far more disturbing
Around two hours later, shortly after 11 p.m., a similar figure appeared on WTTW. Contemporary reporting places the start at about 11:10 p.m.
This time the target was WTTW during a late-night airing of Doctor Who.
This interruption ran for about ninety seconds. A distorted voice could be heard. Years later WTTW air director Paul Rizzo recalled that staff in master control could see what was going out and could not immediately replace it with the scheduled programme.
The masked figure mocked television personalities, referenced advertisements, shouted nonsense phrases, and rambled in a warped voice while swaying in front of the camera.
The masked performer gestured with a soft-drink can and made references to television advertising. The recording establishes what was shown without explaining why the performer chose those references.
Then the broadcast took an even stranger turn.
Near the end of the recording, someone off camera struck the masked performer with what appeared to be a flyswatter. According to WTTW, the interfering signal stopped on its own. Doctor Who returned. The programme gave no explanation for the pictures that had displaced it.
Who was Max Headroom?
To understand why the hijacking became so iconic, it helps to understand the character being impersonated.
Max Headroom was a fictional media personality created in the 1980s.
The character appeared computer-generated, spoke with stuttering glitches, and acted as a satirical symbol of television culture and corporate media.
At the time, Max Headroom was everywhere — TV shows, music videos, commercials, and pop culture references.
Which made the hijacking even more surreal.
The intruder wasn’t dressed as a monster or a political figure.
They chose a character already associated with distorted media and artificial television culture.
That detail has fueled theories for decades.
How did someone hijack live television?
Station engineers pointed to the microwave link that carried a programme from the studio to the transmitter. A competing signal could account for pictures reaching viewers even though the station staff were still running the normal programme. That was an engineering explanation, not the recovery of the intruders’ equipment. The transmitting location and hardware were never publicly established.
The FCC investigation
The Federal Communications Commission investigated. Contemporary reporting quoted its Chicago office saying viewers had offered recordings. Those tapes preserved the interruptions and gave investigators the same problem viewers had faced. They could see a disguise, a moving backdrop and, in the second segment, parts of a performance. The recordings did not identify the people responsible.
What the recording can tell us
The two interruptions were close enough in time and appearance for engineers and reporters to treat them as connected. Their differences are revealing. WGN restored its programme during the brief first intrusion. At WTTW, the longer recording ended before staff could take back the picture. Neither sequence supplies the identity or motive of a participant.
The television character gave the intrusion an immediately recognizable face. The person behind the mask remains unknown. Suggestions involving an employee, a technical hobbyist or a deliberate piece of media satire have never supplied a verified identification.

Why the footage still unsettles people today
The surviving tapes make it possible to watch the night in sequence. On one channel, the sports reporter comes back after an interruption measured in seconds. On the other, a familiar programme resumes after the interfering transmission ends. Both broadcasts returned to normal. The face viewers remembered belonged to a fictional character, the one participant whose identity everybody already knew.
What remains unresolved?
WTTW’s staff could later describe the interruption from inside master control. Engineers could explain a plausible weakness in the route from studio to transmitter. The remaining gap lies between that technical possibility and the people who used it. The recordings preserve their work without establishing their names.
