I've seen each and every single episode of Gimme A Break!, and Mama's Family. I've also seen the 2-hour Knight Rider pilot movie Night of the Phoenix; A Smurfs Christmas; and The Kid with the 200 IQ with Diff'rent Strokes' Gary Coleman, Benson's Robert Guillaume, and Gimme A Break!'s Kari Michaelsen. All which aired on NBC that season.
There seems to be some confusion as to when the Mississippi was adopted as the dividing line, but it appears the line between K and W was farther west until around the mid 1920s. WMT, WOI, WHO, WOC and WOW all started as AM stations in that decade. Even well after that, the FCC still allowed the occasional exception, which is why Omaha still has a WOWT-TV even after being forced to rename itself upon splitting from WOW radio (based on the rules at the time).
