I don't know about the "19 channels" figure, but co-channel interference
*was* a problem for analog TV. I used to live in a sort of "between
markets" area, which resulted in us receiving both broadcast channels 5
and 6. There was always "venetian blind" interference from their video
signals interfering.
Shortly after, we had an FM station go up nearby, and that interfered
with channel 6 as well. I had to install an FM trap to clear it up.
