What happened
Max Headroom was a fictional, computer-generated television host, played by actor Matt Frewer in a prosthetic mask and famous in the mid-1980s for his stuttering delivery and a Coca-Cola advertising campaign. On the evening of Sunday, November 22, 1987, a person wearing a rubber Max Headroom mask and a yellow blazer briefly became the only thing on two Chicago channels.
The first break-in hit WGN-TV, channel 9, at about 9:14 p.m. during the sports portion of its Nine O’Clock News. Highlights of a Chicago Bears game cut out and were replaced by the masked figure rocking from side to side in front of a sheet of corrugated metal that mimicked the moving background of the real character. There was no intelligible sound, only a buzz. The intrusion lasted roughly 25 to 30 seconds before the station’s picture came back. Sports anchor Dan Roan told viewers he was as puzzled as they were.
About two hours later, at around 11:15 p.m., the same figure appeared on WTTW, channel 11, the city’s PBS station, during an episode of the Doctor Who serial Horror of Fang Rock. This time the audio came through, although heavily distorted. Over roughly 90 seconds the figure mocked WGN sportscaster Chuck Swirsky, recited a Coca-Cola slogan associated with the real character, and rambled through a string of disconnected remarks and jokes. The segment ended with the masked person’s bare backside being swatted with a fly swatter by a second participant. The hijackers cut their own feed, and the Doctor Who episode resumed.
The investigation
The two stations were vulnerable in the same way. Both sent their programs from studios on the North Side to transmitters on downtown skyscrapers over a microwave studio-to-transmitter link: WGN to the top of the John Hancock Center and WTTW to the Sears Tower. The accepted explanation is that the intruders aimed a stronger microwave signal at the receiving dish, overpowering the station’s own feed. WGN engineers ended the first attack by switching the frequency of their link. At WTTW nobody was on duty at the transmitter site late on a Sunday night, so no one could intervene, which is why the second intrusion ran so much longer.
The Federal Communications Commission opened a criminal investigation the next day, and agents from the FBI’s Chicago office joined it. An FCC spokesman quoted a maximum penalty of a $100,000 fine, a year in prison, or both. Investigators reasoned that the operation needed a line of sight to the downtown towers, probably from a high point on the city’s North or Northwest Side, and equipment that a knowledgeable amateur could have assembled for a few thousand dollars. Michael Marcus, who led the inquiry from FCC headquarters, later said that the Chicago field office was reluctant to canvass neighborhoods and that few resources were committed to a case in which no one had been hurt. No arrest was ever made, and the federal statute of limitations ran out in 1992.
The explanations
Because the case was never solved, theories have filled the gap. The most durable is that an insider was involved. Rick Klein, who runs the Museum of Classic Chicago Television, and other researchers have argued that someone with a connection to WGN, perhaps a current or former employee with a grievance, is the likeliest candidate, and engineers at both stations have reportedly told them that a complete outsider would have struggled to pull it off.
A second theory was promoted in a widely shared Reddit post by Bowie Poag, who claimed that two brothers from Chicago’s hacker and bulletin-board scene, whom he called J and K, were responsible. Poag offered no physical evidence, the brothers never responded to journalists, and he later said he no longer considered them suspects. A rumor that the late performance artist Eric Fournier was behind the mask has been denied by a former bandmate. None of these ideas has been supported by documents or a confession.
Where it stands
Recordings of both intrusions survive because viewers were taping at home, and the WTTW clip has circulated widely online. The FCC and FBI files have never produced a name, and journalists who revisited the case for its 25th and 30th anniversaries, including Chris Knittel for Vice in 2013 and WBUR’s Endless Thread in 2019, found former investigators who believed there had been workable leads that were never followed. The hijacking stands as a real, documented event with an unknown author: a short, crude piece of television that exposed how easily an analog broadcast chain could be seized and that nobody has ever claimed.
