On January 24, 2006, the Warner Bros. unit of Time Warner and CBS Corporation announced that the two companies would shut down The WB and UPN and combine the networks' respective programming to create a new "fifth" network called The CW. With the announcement, Tribune Broadcasting signed ten-year agreements for KTLA and 16 of the company's 18 other WB-affiliated stations (three of which it would sell to other groups shortly before The CW launched including WLVI, WATL, and WCWN) to become charter affiliates of The CW. The station changed its branding to "KTLA 5, The CW" on September 17, 2006 immediately after the airing of The WB's final broadcast, "The Night of Favorites and Farewells".
