Here’s a sight you honestly don’t see much anymore at a TV station – a videotape cassette. Specifically, one of Brain Maker with David Perlmutter, MD. If you’ve ever seen this pledge special, it’s entirely possible it was broadcast from this source.
In the early days of television, all programming was broadcast live but the introduction of magnetic tape in the broadcast industry allowed programs to be recorded and shown later. Over the years, the videotape sources have changed and this is probably one of the last to be used here at the station. Most of the shows you watch on the services of UNC-TV these days air from digital or satellite sources and not from tapes like the one seen above.
