Founded in 1988, the station was owned by WLIG (now WLNY-TV) Inc. It was an independent translator station out of Mineola, NY, after W44AI (now WNYX-LD) moved the license to New York City as an independent station airing public access TV. In the following years, the call letters changed from WLIG-LP, WLNY-LP, and back to the original call sign of WLIG-CD in 2010. Despite the call changes, the programming stayed much the same. After WLNY-TV announced the station’s sale to CBS, the translator station was sold to Local Media in 2012 and temporarily ceased broadcasting.
In mid-2012, the call letters changed to WMUN-CD, and the station began running Classic Arts Showcase full-time. By late 2012, CAS was dropped and the station began airing infomercials. The following year, children’s programming was added to fulfill E/I requirements, plus locally produced programming such as Community Impact. In the summer of 2014, The Balancing Act was added to the station’s afternoon lineup.
Community Impact was moved to late afternoons in 2015, and additional children’s programming was added for an hour on weekday and weekend afternoons, thus exceeding the E/I requirements. A few weeks later, the children’s programming, along with public affairs programming, was dropped and the station began to air infomercials full-time. The following year, E/I programming returned on the air.
On April 13, 2017, the Federal Communications Commission (FCC) announced that WMUN-CD was a successful bidder in the spectrum auction, and would be surrendering its license in exchange for $23,191,413. Local Media TV surrendered WMUN-CD’s license to the FCC for cancellation on August 28, 2017.
The station’s digital channel is multiplexed:
In March 2015, home shopping channel Jewelry TV was added to the station’s 45.2 sub-channel under the name WMUN-2.
