The hype around Disco and the resulting backlash were so intense that people lost sight of what actually happened. Discotheques were a cultural trend that started in the 60's and went big in the 70's, and it was an international phenomenon that included Europe and Latin America before it spread into the US.

If you watch Saturday Night Fever and pay attention, you will notice that people tend to forget what the movie was actually about: A group of Italian American teenagers living in the Bay Ridge section of Brooklyn in the late 70's who used the then-vibrant Disco scene as an escape from their otherwise problematic lives. It's a pretty messed-up movie.

And Disco didn't die, it just evolved into the 1980's club scene. When Michael Jackson worked with Quincy Jones to make Off The Wall, he pointed the way for an entire decade that was still in the future.
