WDIV-TV virtual channel 4 (UHF digital channel 45) is an NBC-affiliated television station located in Detroit, Michigan, United States. The station serves as the flagship broadcast property of the Graham Holdings Company subsidiary Graham Media Group. WDIV maintains studio facilities – which also house the headquarters of Graham Media Group – located on West Lafayette Boulevard in Detroit. As such, WDIV-TV is the only major television station in the market whose offices and studios are located in Detroit proper, while the market's other television stations are located in Southfield (WDIV's transmitter is, however, located on Greenfield Road in Southfield).
On cable, the station is available in standard definition on channel 14 on Comcast Xfinity's Detroit city system, channel 9 on Xfinity's South Oakland County system, channel 4 in other suburbs and outlying areas and on AT&T U-verse, and channel 5 on Cogeco's Windsor system, and in high definition on Xfinity channel 232, Cogeco channel 714, and AT&T U-verse channel 1004.
The station first signed on the air as WWDT on October 23, 1946 for one day of demonstrative programming; regular programming commenced on March 4, 1947. It was the first television station in Michigan and the tenth station to sign on in the United States overall. The station was originally owned by the Evening News Association, parent company of the Detroit News, along with WWJ radio (AM 950 and FM 97.1, now WXYT-FM). On May 15, 1947, the television station changed its call letters to WWJ-TV to match its radio sisters. Channel 4 has always been an NBC affiliate owing to WWJ radio's longtime affiliation with the NBC Red Network although it aired some programs from the DuMont Television Network prior to WJBK-TV (channel 2)'s sign-on in October 1948.
