Turner's media empire began with his father's billboard business, which he took over at 24 after his father's suicide. The business, Turner Outdoor Advertising, was worth $1 million when Turner took it over in 1963 (roughly $7.7 million in present day terms). Purchase of an Atlanta UHF station in 1970 began the Turner Broadcasting System. Cable News Network revolutionized news media, covering the Space Shuttle Challenger disaster in 1986 and the Persian Gulf War in 1991. Turner turned the Atlanta Braves baseball team into a nationally popular franchise and launched the charitable Goodwill Games. He helped reinvent interest in professional wrestling when he owned one of the most popular wrestling companies of the middle to late 1990s known as World Championship Wrestling (WCW). The Monday night show that it put on was the highest rated on cable and helped boost Turner's channels of TNT and WTBS.
Turner's penchant for controversial statements earned him the nicknames "The Mouth of the South" and "Captain Outrageous". Turner has also devoted his assets to environmental causes. He was the largest private landowner in the United States until John C. Malone surpassed him in 2011. He uses much of his land for ranches to re-popularize bison meat (for his Ted's Montana Grill chain), amassing the largest herd in the world. He also created the environmental-themed animated series Captain Planet and the Planeteers.
