Ted Turner's 25-year-old son is leaving the nest and going to work for another cable television company. Robert Edward Turner IV, known to most as Teddy, will be a sales and marketing executive with the Country Music Television network in Nashville, Tenn., after a career that included stints as Moscow correspondent for his father's empire, which includes Cable News Network and WTBS. "I'm going to a small outfit with a great deal of potential," Turner, who started working for his dad at 16, told the New York Daily News. "It's an opportunity to take something small and make it big. This place (the Turner empire) is already big. I've got Dad's blessing."
