Turner Broadcasting System, Atlanta, GA
After rebuilding his late father's outdoor advertising business in Atlanta, Turner acquired a failing independent TV station in 1970, successfully upgraded its programming and bought Major League Baseball's Atlanta Braves franchise. Recognizing cable TV's potential, he ignored naysayers and rented satellite transmission time to transform WTBS into the nation's first cable superstation. WTBS aired baseball and commercials across the land. He next created the all-news, all-day Cable News Network and TNT cable network; bought Hanna-Barbera's cartoon studio and MGM's film library; and in 1995 merged his media company with Time Warner to create a $17 billion conglomerate.
