 WISR was one of these stations, and prior to the nighttime authorization, had never used satellite technology on the air, relying on world and national news via UPI wire service.After nighttime power was granted, WISR signed an affiliation agreement with CBS news, introducing satellite technology to its listeners.Joel Rosenblum continued to operate WISR out of its original studio on North Main Street in downtown Butler until 1997, when he agreed to sell the station to Brandon Communications Systems, Incorporated.
