First discovered shortly after Charlie Ginsburg invented the first video recorder for Ampex in 1956, video feedback was considered a nuisance and unwanted noise. Technicians and studio camera people were chastised for allowing a video camera to see its own monitor as the overload of self-amplified video signal wreaked havoc with the 1950s video pickup, often ruining the pickup. It could also cause screen burn-in on a playback TV and/or monitors of the time as well, by generating static brightly illuminated display patterns.
