WGEM-DT2 began broadcasting as a WB affiliate in September 1998. It was a cable-only station, and as a result, had the fictional call letters "WEWB". The station was part of The WB 100+ group. Fellow CW affiliate WCWN in Albany, New York, held the actual WEWB call sign when it was a WB affiliate. Prior to September 1998, the Quincy market received WB programming on cable via the national feed of Chicago-based WGN-TV, which carried WB programming until 1999. Following the 2006 merger of UPN and the WB, "WEWB", which began using the WGEM-DT2 callsign in an official manner, began airing programming from The CW. The station became part of The CW Plus, a service that is a similar operation to The WB 100+. Like all CW Plus affiliates in the Central Time Zone, WGEM-DT2 aired the nationally syndicated morning show The Daily Buzz on weekdays from 5:00 am to 8:00 am.

WGEM-DT3, branded on-air as WGEM Fox, is the Fox-affiliated third digital subchannel of WGEM-TV, broadcasting in 720p high definition on virtual and VHF channel 10.3. The subchannel can also be seen on Mediacom channel 2 in Keokuk, Spectrum channel 12 in Hannibal, Xfinity channel 18 in Quincy, and DirecTV channel 12 throughout the market.

What is now WGEM-DT3 was established in 1994 by Continental Cablevision and WGEM to fill a void in a market where there was no local over-the-air Fox affiliate. Between 1990 and 1994, Fox programming in the market was limited to off-hours on WGEM's analog signal. It was originally a cable-only station; as a result, it was known on-air with the fictional "CGEM" calls based after the "C" in Continental and "GEM" in WGEM. The station, which was the only Fox-affiliated cable channel to have not been a part of Foxnet, began to air on the third digital subchannel of WGEM-TV in 2006. This was one of the first instances of a major network affiliate operating a cable-only affiliate of another network; this would eventually be repeated on a national level with the launch of The WB 100+ Station Group in September 1998. As part of becoming available over-the-air, it began to use the WGEM-DT3 call sign in an official manner; nonetheless, the "CGEM" branding was retained until 2010. The station remains as the only Fox affiliate in the area, although Spectrum in Hannibal also carries KTVI from St. Louis.

The station's digital signal is multiplexed:

WGEM-TV shut down its analog signal, over VHF channel 10, on February 19, 2009, two days after the original target date when full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal relocated from its pre-transition ultra high frequency (UHF) channel 54, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 10.[6][7]
