Lincoln Cablevision (Metrovision) in Nebraska in the 80s and early 90s. Cable was a near-necessity for TV viewing in that market as at the time there was only one in-market TV station and it was over 25 miles west of town, so it was difficult to get a clear picture indoors. Cable brought in all the Omaha signals from 60 miles up the highway that otherwise required a rooftop antenna to receive well. I recall there were also several (at least 4 if not more) local cable-only channels ranging from more basic government and school programming to local news, entertainment and sports programming as well. That system went to Time Warner Cable in the mid-90s if I remember right, and so of course is now Spectrum. Last I watched anything on that system a few years ago, all the interesting local cable-only programming seemed to be gone, and Lincoln now has an in-market station for each major network so redundant out of market programming has been dropped except for Fox.
In the early 90s I also remember tiny Harmon Cable in western Sarpy County, Nebraska. 330 MHz, I think. Changed hands to become Galaxy and now Zito. The last time I saw anything on it was around 2006 and it still used a WeatherStar III for The Weather Channel local content.
