Around 1974 I moved to a new apartment that had cable TV as part of the rent. My recollection was that it was a two coax line with switch affair. You essentially had two feeds. At some point, the owners decided that cable was available only as an extra payment, so they came and disconnected the switch and the connections into the coupler in the wall cavity, but leaving the coupler. I simply reconnected a length of cable to the coupler after they'd gone. They never knew about it. Around 1980, I had my own house and wouldn't let the cable guys anywhere near it.
That was when there still was decent broadcast content. Today, it seems that broadcast TV is mostly reruns and lots of commercials--and 6 hour golf tournaments. If something is advertised on broadcast TV, it's probably (a) overpriced or (b) a scam. The secondary channels (e.g. MeTV, iON Comet, Grit, Bounce, etc.) are even worse.
