I was a teenager in the 80s when it dawned on me that, during a live broadcast, the electron beam in the CRT was literally being driven, in realtime and over radio, by the camera at the broadcast site. Of course, any respectable broadcaster also had tons of video processing equipment to sync those non-synchronized camera signals ... and to delay the actual transmission for whatever reason (censoring, etc.)
