On November 2, 1993, the Warner Bros. Television division of Time Warner and the Tribune Company announced the formation of The WB Television Network. Due to the company's ownership interest in the network (initially a 12.5% stake, later expanding to 22%), Tribune signed its seven existing independent stations (one such station, Atlanta's WGNX, joined CBS instead one month prior to The WB's launch), along with an eighth that the company had acquired the following year, to serve as The WB's charter affiliates. With this, KTLA became a network affiliate for the first time in 47 years when The WB launched on January 11, 1995.
