MaxHeadroomsignalhijacking

The Max Headroom signal hijacking (also known as the Max Headroom incident) was a hijacking of the television signals of two stations in Chicago, Illinois, on November 22, 1987, that briefly sent a pirate broadcast of an unidentified person wearing a Max Headroom mask and costume to thousands of home viewers.

A criminal investigation conducted by the Federal Communications Commission in the immediate aftermath of the intrusion could not find the people responsible and despite many unofficial inquiries and much speculation over the ensuing decades, the culprits have yet to be positively identified.
