On November 22nd 1987 somebody hijacked the television feeds of WGN and WTTW in Chicago. The person was wearing a rubber mask of Max Headroom, a character popularized by actor Matt Frewer in various TV Shows and commercials through the 80′s, and made a number of pop culture references from the time. In order to hijack the feed they had to patch directly into the signal transmitter on top of the Sears Tower. WGN was able to switch to an alternate feed, only showing a few moments of the broadcast before returning to it’s original programming, but WTTW’s airing of Doctor Who was interrupted for a minute and a half before the hijacker presumably ended their broadcast.

The perpetrator was not caught and remains unknown to this day.
