Turner Broadcasting System, Inc. is the Time Warner subsidiary managing the collection of cable networks and properties launched or acquired by Robert Edward "Ted" Turner starting in the mid-1970s. The company has its headquarters in the CNN Center in Atlanta, Georgia. TBS, Inc. merged with Time Warner on October 10, 1996, and now operates as a semi-autonomous unit of Time Warner. This would be Time Warner's second foray into cable broadcasting, after owning the Warner-Amex Satellite Entertainment Company through Warner Communications before selling it to MTV Networks in 1987.
