WGN-TV
The first occurrence of the signal intrusion took place during WGN-TV (channel 9)'s live telecast of its primetime newscast, The Nine O'Clock News. During Chicago Bears highlights in the sports report, the station's signal was interrupted for about half a minute by a video of a person wearing a Max Headroom mask, standing in front of a swaying sheet of corrugated metal, which imitated the background effect in the Max Headroom TV and movie appearances. There was no audio, only a buzzing noise. The hijack was stopped after engineers at WGN switched the frequency of their studio link to the John Hancock Center transmitter.
The incident left sports anchor Dan Roan flustered, saying, "Well, if you're wondering what happened, so am I."
