When I watched PBS programs, there was always a long pause between the programs. I remembered watching my teacher rewind the movie reels in class, and stick another film on the projector. I imagined that was what was happening at the studio during those long pauses...the people in the studio were re-winding the movie, and sticking a new one on. Now that I am a broadcast technician by trade...I know what I thought was actually occuring...because TV programs back when I was growing up actually did come off of movie reels. Nowadays though, they come off of videotape. I also thought if you held a piece of videotape up to a bright enough light, you could see the pictures on it, just like on a piece of movie film
