When I first got into radio (1971), we had to do a Legal ID as close to the top and bottom of the hour as possible that didn't interrupt the flow of the program, per FCC rules. It was the Call Sign immediately followed by the city of license. Anything else was not required, but allowed. For example, any of these were fine:
"WABC, New York"
"Playing your favorite music, this is MusicRadio 77, WABC, New York."
"WQXI / WQXI-FM, Atlanta"
"We are Super 79, KULF, Houston"
I never worked at a station with a translator, and HD was in the future back then. Eventually the rules were relaxed to only a top of hour ID, but station imaging made it almost redundant.
