You guys are too young. I watched my first tv show when the CBS station came on the air in Shreveport, LA. Howdy Doddy was popular as was a few other shows. Most were done in front of live audiences.
Yet the TV we had was a Philco with a screen about the size of the stormscope a plane. This was in 1951. We had rabbit ears for an antenna. On Friday nights, we watched live boxing from NYC. The neighbors came over to watch it with us. Commercials were done live. Tommy Sands was living here then and he advertised cars for a local dealer. He always pounded on the fender to show how tough the cars were. One night a car had been rigged so when he hit the fender, it fell off the car. The station really should have had a delay on the sound as we got to hear some words that were not common for the day.
