Episode made for a particular season, but airs as part of another season in the series.
Sometimes, a show can air episodes Out of Order. For a show where continuity doesn't matter much, it's not really a major issue about broadcast order. But on a show with a Story Arc, it can be an issue having episodes held over between seasons. It's sometimes easy to spot a holdover episode due to filming differences or animation differences between seasons; that's often the most obvious visual clue. Sometimes even characterization changes between the seasons. Live Action TV
- Lucifer had episodes that were made for Season 2, but Season 2 was Cut Short, meaning that the episodes aired as part of Season 3.
- Police, Camera, Action! had the episodes "On The Buses", a holdover from Season 6 in 1998 (eventually airing on 6 January 1999, and not December 1998 as planned), and the Extra Long Episode which was a partial Clip Show, "Learning the Hard Way", which aired on 19 January 1999 (meant for Christmas Day 1998 as a pseudo-Christmas Episode, but didn't air then).
- King of the Hill 's Season 10 was mostly holdover from Season 9 due to the production cycle, although not Troubled Production.
- Some of Season 2 of Steven Universe were holdovers from Season 1.
- The Simpsons had a lot of these, of which 113 episodes have aired. You can find more information about them here. Due to the show's status as a Long Runner, this happened anyway. Given that the show has Negative Continuity, perhaps it shouldn't be an issue.
