Flint Broadcasting Limited Partnership requested a station with the call letters WSMH,[2] which were assigned on September 27, 1984.

[8] Sinclair announced numerous layoffs at WSMH/WEYI in March 2023, which led to a major cut in news production from the stations.

[11] In January 2006, Sinclair announced plans to end its News Central operation due to low ratings and expense.

On April 10, Sinclair announced that CBS affiliate WNEM-TV would begin producing a nightly 10 o'clock show on WSMH known as TV 5 News at 10 on Fox 66.

Even after WSMH shut down its news operation, Mark E. Hyman's controversial "The Point" editorials continued to air following the end of the WNEM-produced newscasts.

Effective April 27, 2015, WEYI took over duties of producing the 10 p.m. newscast for sister Sinclair station WSMH, Fox 66 News at 10.

[13] Full Measure with Sharyl Attkisson, a Sinclair Broadcast Group produced half-hour investigative news program, airs on the channel on Sunday morning starting October 4, 2015.

[14] The station's signal is multiplexed: On September 30, 2006, WSMH began broadcasting The Tube on its secondary subchannel.

[16][17] In late August 2012, TheCoolTV was dropped from all 32 Sinclair stations that carried the channel, including WSMH, with no replacement due to non-renewal of affiliation.
