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!
