This is a bit of an ad, but I swear I don’t sponsor H&I. I just use them a lot. My wife and I bought “bunny ears”/an antenna for our TV when we lived in the Midwest. We also watch H&I on the west coast. Almost every night they play one episode from each popular, live-action, series in order of production: TOS, TNG, DS9, Voyager, Enterprise. The start time depends on your location, but I believe it starts around 7pm Central Time.
It has commercials, but I don’t mind since the shows are “free” over the airwaves. I haven’t tested in the east coast but I bet a lot of the country has some coverage.
Our antenna also has some MacGuyver, Stargate, Baywatch, and some other popular old shows. I just think it’s cool that we can have access to such great shows with a one-time cost (and commercials). It’s also great because it works during internet issues (as a backup if streaming is failing). My wife and I often just left it on in the background while we worked or made dinner!
I “cut the cord” many years ago, and instead installed an OTA antenna in my attic. There are still many stations even in my area that carry all these great shows, and I still have a lifetime sub TiVo I use to record anything new (or old) I might want to watch.
