A black and white TV is just like the digital cable flatscreen high definition 798 channel thing mounted on your wall, except… It was a box about the size of a small refrigerator, there was no remote – to change channels you actually not only had to stand up but you had to walk to the TV & spin a dial, there were only 5 channels not 798, the picture on the screen was in shades of white gray & black like a security monitor, the picture had NO COLOR, it was ALL in shades of gray. It was superior technology at the time. We watched the original Star Trek, Get Smart, the Wild Wild West & other shows that you can now watch on DVD or as a cinema movie. We could only record sound on our cassette tape recorders, we could not record video. Home movies were on large reels of film that would be passed between a light & a lens in a home “movie projector” (if you could afford one) & the movie would be shined onto a roll- up screen on the wall like a window shade.
