deceased Rob Parker – sports anchor, also co-host of Sports Final Edition, now retired Anne Thompson – reporter (1986–1997; now at NBC News as correspondent for NBC Nightly News) Reynolds Wolf – meteorologist (1999–2002, joined CNN; currently on The Weather Channel) Van Earl Wright – sports anchor (1993–1996, was lead announcer of NBC's 2008 revival of American Gladiators) Technical information Subchannels The station's digital signal is multiplexed: WDIV's second digital subchannel formally carried programming from NBC Weather Plus, which folded in November 2008. WDIV-TV also has a Mobile DTV feed of subchannel 4.1, labelled "Local 4", broadcasting at 1.83 Mbit/s. WDIV-DT2 is one of the few affiliates of This TV to have been affiliated with the network through most of its entire history, even as it was dropped in several other markets before Allen Media Group purchased the network in 2021. On July 30, 2015, WDIV-TV became the market's affiliate for Weigel Broadcasting's MeTV network through their third subchannel. WDIV-DT3 is used as an overflow feed for network and syndicated programming if the latter is pre-empted by breaking news and severe weather coverage on 4.1. On January 3, 2020, WDIV-TV activated a fourth subchannel, which broadcasts Cozi TV, a network owned by NBC's parent company NBCUniversal. This makes WDIV-TV the third station in the Detroit market to have been affiliated with Cozi TV, which was previously on WMYD and on WADL. Analog-to-digital conversion WDIV-TV signed on its digital high-definition signal on UHF 45 on March 1, 1999. The station shut down its analog signal over VHF channel 4 on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal continued to broadcast on its pre-transition UHF channel 45. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 4. As part of the SAFER Act, WDIV kept its analog signal on the air until June 26 to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters. In March 2017, the station announced that it would move its physical RF channel to UHF channel 32. Out-of-market coverage WDIV's over-the-air signal can be picked up as far away as Flint, Lapeer, and Adrian in Michigan, as well as Toledo, Ohio and even London, Ontario.
