In January 1950, Belo purchased KBTV from Lacy-Potter for $575,000; the sale received FCC approval on March 13, 1950, with Belo formally assuming control of Channel 8 on March 17. The station was the first television property to be owned by the Dallas-based company, and also served as the flagship station of its broadcasting division until Belo merged with the Gannett Company in 2013. Four days later on March 21, Belo changed the station's call letters to WFAA-TV to match those of its new radio partner WFAA (570 AM, now KLIF). The WFAA calls reportedly stood for "Working For All Alike," although the radio station later billed itself as the "World's Finest Air Attraction" (the KBTV call letters were later used from 1953 to 1984 by what is now sister station KUSA in Denver, and since 1999 are used by a Fox-affiliated television station in Beaumont). WFAA is one of a relatively limited number of broadcast television stations located west of the Mississippi River whose call letters begin with a "W"; the FCC normally assigns call signs prefixed with a "K" to television and radio stations with cities of license located west of the river and broadcast call signs prefixed with a "W" to stations located east of the river. The anomaly in the case of the WFAA television and radio stations is due to the fact the policy predates the launch of the former, as Dallas was originally located east of the original "K"/"W" border distinction defined by the FCC.
