Without Googling anything to confirm this I'll tell you guys what I know about disco in the 1970's Chicago.
I think Disco was developed by the Gay community in New York. It was their club dance music. It spread from there.
In Chicago where I lived it became very popular. As far as I know it spread into the Gay clubs first then into mainstream clubs. It was dance Music.
I really don't remember to many Bands playing it. It was usually a DJ spinning LP's.
In Chicago it started taking over everywhere. The girls loved it because it was so danceable and most guys soon learned to dance Disco too so they could get the girls.
In the 70's I was into the club scene a little myself. I was Married and my wife and I liked to go out once in a while with our friends. ALL the clubs and Bars played Disco then and every one was dancing Disco.
By late 70's a lot of people in Chicago were sick of it. It's all you heard.
You could still hear Popular Music on the radio too but Disco was always there.

People were getting pretty sick of it by the late 70's. Disco Sucks became a slogan. I remember bumper stickers with Disco Sucks.
In 1979 a Chicago DJ named Steve Dahl held a publicity stunt in Cominskey Park in Chicago. He was going to blow up a Crate of disco records during the break between a double header Baseball game.
They expected about 15000 fans to show up. What they got was about 100,000 people showed up. People brought their own Disco Albums and were throwing them like frisbies in the stadium. a few people were even hurt by flying Disco LP's. Dahl rigged a big crate full of LP's with explosives and exploded them on the field. The whole thing turned into a near riot. Screams of Disco Sucks were heard all night long around the stadium.
This backlash against Disco actually succeeded in its demise.
Thing is In the early 70's it was pretty popular but people just got sick of it.
