It’s odd that The Diplomat in my Next Airing list is after Coupling. Coupling ended like 12 years ago (at least) and The Diplomat is coming back in a year or so.
I’d move the ended shows to the bottom of the list in a separate visual block called “Ended shows” or something.
How about three blocks: No label for shows that have definite next airing dates, “Upcoming” for shows that are in progress but don’t have definite air dates and “Ended” for shows that are done.
