During the 70s and 80s a new phenomenon appeared. Television Hijacking. It started in 1977 when a man in England hijacked the sound broadcast of a newscast. In 1986, a hijacker known as Captain Midnight hijacked HBO in response to their scrambling of television signals. The year after (20 years ago as of today), a character disguised as Max Headroom (a television character) infiltrated two Chicago television studios in one night. First the man infiltrated Channel 9 (WGN) for a few seconds with no sound, and then moved on to attack another Chicago station, this time with sound. After the Max Headroom incident, television hacking incidents were rare in the United States except for this one in Wyoming.
