ELI5: I've seen tons of "music videos" that predate the 80s. Where would people watch these videos before MTV?

The earliest videos were often just of the band doing a number and weren't really a 'story'. They'd often be shown as part of a TV special such as them being a guest on a variety show. Some were part of a dedicated movie. The Who's "Tommy" in 1975 or some of the Beatles and Elvis films were examples. 

Later on as 'videos' started to take off, they had a half-hour or hour-long sometimes-hosted show that was dedicated to playing a variety of those videos, usually airing on Friday and Saturday nights. 

Then MTV and its variants came along and kind of killed those shows.
