One of the most legendary radio stations in the world has a new owner. And for a change, it's not one of the big radio conglomerates. Instead it's a billionaire who made his fortune in supermarkets and real estate. WABC was the most listened to radio station in North America in its rock days.

Its ratings as a talk format are still pretty good and it claims to be the most streamed station in the U.S. 

The oddity: the new owner has a talk show of his own but on a rival station. How long before he carves out some 77 goodness for himself?

By the way, worth noting that this isn't the only big outlet Cumulus has sold off this year. Long time rocker WPLJ, which used to be WABC-FM, left the air on May 31st and is now an all-Christian format.
