The Hannington transmitter, from where the broadcast signal was hijacked
Date 26 November 1977
Location Southern Television
Participants Unidentified
Outcome Unsolved

The Southern Television broadcast interruption was a broadcast interruption through the Hannington transmitter of the Independent Broadcasting Authority in the United Kingdom at 5:10 p.m. on 26 November 1977. The broadcast message is generally considered to be a hoax, but the identity of the hijacker is unknown.


A speaker interrupted transmissions for six minutes and claimed to be a representative of an "Intergalactic Association". Reports of the incident vary, some calling the speaker "Vrillon" [1] or "Gillon", others "Asteron". [2] [3]

The voice, which was disguised and accompanied by a deep buzzing, broke into the broadcast of the local ITV station Southern Television, overriding the UHF audio signal of the early-evening news being read by Andrew Gardner from ITN to warn viewers that "All your weapons of evil must be removed" and "You have but a short time to learn to live together in peace."

The interruption ceased shortly after the statement had been delivered, transmissions returning to normal shortly before the end of a Looney Tunes cartoon. Later in the evening, Southern Television apologised for what it described as "a breakthrough in sound" for some viewers. ITN also reported on the incident in its own late-evening Saturday bulletin.

The broadcast took over the sound only, leaving the video signal unaltered, aside from some picture distortion.
