That was a trope of real tv shows especially , and also a way to fill time with less filmed content i.e cost cutting. Often you’d see many shots 5-7 times throughout the show. Opening montage , before ad tease, after ad recap, thr event itself, end of show montage summary etc. Also drives me nuts. Even back when ads were between. “Yes I know what happened two minutes ago!”. And then there were so many shows you could tell the edit project file was a template and they just replaced the footage. Same exact structure every episode.
Cool thing about this is they could assemble these bundles into parallel live streams we could simply flick between to find what we prefer to watch. If they run into a problem of people flicking away when ads run then just align the ads to run at the same time on each “channel” if I can call them that ?
