The two stations share studios and transmitter facilities on Crestview Circle, in unincorporated Lauderdale County, south of Meridian.

The analog channel 30 allotment remained dark until WLBT in Jackson filed for a new station to serve eastern Mississippi in December 1980; a construction permit was issued on September 14, 1981.

WLBM's studios caught fire on April 17, 1990, knocking the station off the air and leaving much of Eastern Mississippi without an over-the-air NBC affiliate.

NBC returned to the market when Global Communications bought the dormant channel 30 license and resumed operations as WGBC on September 15, 1991.

In January 2008, local businessman Michael Reed (owner of Waypoint Media) bought WGBC and renewed the LMA with WMDN.

In late 2008, WGBC picked up the Fox affiliation for Meridian on its first digital subchannel with the Retro Television Network (RTV) airing during non-network time periods.

In fall 2010, WGBC's main signal had acquired enough first-run syndicated programming that Retro TV was dropped from the station, and took on a full-time branding of "Fox 30".

As was the case with WGBC's earlier attempt at operating a news department, WMDN was forced to shut down its own newscast production efforts in 2005, being unable to compete with WTOK and maintain consistent viewership.

A few years later, WGBC and WMDN began airing five-minute local weather cut-ins during the NBC and CBS national morning shows on weekdays.

Although this would be discontinued, the two outlets continue to air a cut-in branded as The Morning Report with Angie Denney featuring a listing of community events.
