On September 21, 1923, WTAR signed on the air at 780 kilocycles with 15 watts of power. It was the first radio station to go on the air in Virginia. On July 6, 1934, WTAR became an affiliate of the NBC Red Network after dropping the CBS Radio Network. At that time, the station was owned and operated by the parent company of the Norfolk Ledger-Star and The Virginian-Pilot. with RDS. By the late 1930s, WTAR got a power boost to 5,000 watts by day, 1,000 watts at night. In the 1940s, the nighttime power was increased to match the daytime power, 5,000 watts. WTAR added an FM counterpart in 1947, 97.3 WTAR-FM, which mostly simulcast the AM station. But few people owned FM radios at that time and WTAR gave up its FM license a couple of years later. The 97.3 frequency returned to the air in the mid-1950s as WGH-FM. In 1950, WTAR signed on a TV station, Channel 4 WTAR-TV. Because 790 WTAR was an NBC affiliate, the TV station primarily carried NBC-TV programs. As the first TV station in the Norfolk area, it also ran some shows from CBS, ABC and the DuMont Television Network. Within a year of the TV station's debut, both the TV and radio facilities moved into a new broadcasting center at 720 Boush Street. In 1961, WTAR management decided to return to FM broadcasting, and signed on a new WTAR-FM, this time at 95.7 MHz. WTAR-FM aired automatedbeautiful music, separate from the AM station, which had a full service format of middle of the road music, news, sports and talk. In the mid-1980s, WTAR switched to oldies music and became an affiliate of CBS Radio News. In the early 1990s, the station stopped playing music and became a news/talk station, adding an affiliation with CNN as well as CBS Radio. Around the same time, rival talk station WNIS got a big boost in power, going to 50,000 watts by day, 25,000 watts at night. Eventually both stations would become co-owned, with Sinclair acquiring AM 850 in June 1997. The following month, on July 15th, WTAR and its new sister station, WNIS, switched dial positions. WNIS moved to AM 790, while WTAR took over the 850 kHz spot on the dial. The move gave WTAR the stronger signal. WTAR flipped from talk radio to an all-sports format on February 5, 2006. On September 15, 2017, WTAR began simulcasting on 106.1 WUSH-HD2 and FM translator stationW243DJ at 96.5 MHz in Norfolk. The move allows WTAR listeners to hear the station on either AM or FM, although the FM translator signal is limited to Norfolk and surrounding communities due to its low power of 120 watts.
