Birth of cable TVIn 1948, cable television was invented by Leroy "Ed" Parsons, (1907-89), who sold electronics and ran a radio station in Astoria, Oregon. On Thanksgiving Day, the Parsonses watched KRSC's inaugural broadcast from the TV station 150 miles away in Seattle. He picked up a usable signal with a large antenna on the roof of the John Jacob Astor Hotel, and strung a coaxial cable across the street to his living room. He placed a TV in the hotel lobby and a TV in a store window. As others in town wanted the same service, Parsons helped them hook into a system using a community antenna on Coxcomb Hill completed Feb 1949. He moved to Alaska in 1953, and by 1967 had installed the state's first cable system in Barrow, Alaska.« |
