WJLA-TV (channel 7) is a television station in Washington, D.C., affiliated with ABC. It is one of two flagship stations of Sinclair Broadcast Group (alongside dual Fox/MyNetworkTV affiliate WBFF [channel 45] in Baltimore), and is also sister to Woodstock, Virginia–licensed low-powered, Class A TBD station WDCO-CD (channel 10) and local cable channel WJLA 24/7 News. WJLA-TV's studios are located on Wilson Boulevard in the Rosslyn section of Arlington, Virginia, and its transmitter is located in the Tenleytown neighborhood of northwest Washington. History The District of Columbia's third television station began broadcasting on October 3, 1947 as WTVW, owned by the Washington Star, along with WMAL radio (630 AM, now WSBN, and 107.3 FM, now WLVW). It was the first high-band VHF television station (channels 7-13) in the United States. A few months later, the station changed its call letters to WMAL-TV after its radio sisters. WMAL radio had been an affiliate of the NBC Blue Network since 1933, and remained with the network after it was spun off by NBC and evolved into ABC. However, channel 7 started as a CBS station since ABC had not yet established its television network. When ABC launched on television in 1948, WMAL-TV became ABC's third primary affiliate; the station continued to carry some CBS programming until WOIC (channel 9, now WUSA) signed on in 1949. During the late 1950s, the station was also briefly affiliated with the NTA Film Network. In 1975, Houston businessman Joe Allbritton, the owner of the now-defunct Washington-based Riggs Bank, purchased a controlling interest in the Stars media properties, which by that time also included WLVA radio and WLVA-TV in Lynchburg, Virginia; and WCIV in Charleston, South Carolina. As a condition of the purchase, Allbritton was given three years to break up the Washington newspaper/broadcast combination, which the Federal Communications Commission (FCC) was seeking to prohibit under the tightening of its concentration of media ownership policy. WMAL-TV was separated first from its radio sisters when ABC purchased WMAL radio in March 1977. As FCC regulations at the time prevented separately-owned stations from sharing the same call sign, WMAL-TV became WJLA-TV, after Allbritton's initials. In April 1977, Allbritton negotiated a deal to trade the station to Combined Communications Corporation in return for KOCO-TV in Oklahoma City, but called off the deal due to last-minute complications despite receiving FCC approval. Allbritton instead sold the Washington Star to Time Inc. in January
