There was a time when the headquarters of the three major networks were located a few blocks from each other. NBC was located at 30 Rockefeller Plaza, and was known as 30 Rock. The ABC headquarters on Avenue of the Americas was called Hard Rock (because of its rock formatted radio stations). And CBS was known as Black Rock because it was made of black stone. Today, ViacomCBS sold off that building as part of its downsizing.

It was built when CBS was a very different company, owning the TV network, radio network, stations, and Columbia Records. In fact at one time WCBS-AM was in the building, so Bill Paley could keep an eye on it. They sold the record label in the 80s. Sold all of the radio a few years ago. They sold Television City in LA last year. So the landscape is very different today.
