I still remember how badly episodes were cut in my market in the ol' days. WPIX would lob off like 5 minutes and they weren't particular about their edits. Sometimes in the middle of a scene or line of dialog. I'll be sitting here these days and still sometimes expect a cut at the end of WNMHGB, just as Kirk says "be it noted she have her life in the performance of her duty," SPLICE! to the exit music and the Enterprise travelling away.
Same story with my local station. They wouldn't edit...they would tear the film to remove scenes. I would cringe in anger every time the station editors would violate my favorite television show.
