I went to college in the late 70s (University of Chicago). We basicly had 2 choices then, LPs or FM. (One kid had reel to reel, and cassete tapes were just happening).
I lived in a dorm that was a converted hotel overlooking lake Michigan (The Shoreland). The hotel had been converted to apartments decades earlier so most dorm rooms had a living room. Pretty much every one of them had an FM antenna taped to the wall above the stereo system.
BTW, almost every living area had a stereo system, almost none of them had a TV. I don’t remember a single one.
