WMUM-TV virtual channel 29 (VHF digital channel 7), is a PBS member television station serving Macon, Georgia, United States and that's the licensed to Cochran. The station is owned by the Georgia Public Telecommunications Commission and it is a sister station to NPR member radio station WMUM-FM (89.7). WMUM maintains studio facilities located on the Mercer University campus on Montpelier Avenue (just east of I-75) in Macon and also there's the secondary offices & studios are located on 14th Street NW in Atlanta, Georgia and its transmitter is located in rural northeastern Bleckley County (northeast of Cochran). The station is operated as part of the Georgia Public Broadcasting television network.


The station first signed on the air on January 1, 1968 as WDCO-TV originally broadcasting on UHF channel 15. In 1990, the station moved its signal to UHF channel 29 in order to avoid interference with a U.S. Department of Defense early warning ballistic missile detection facility that was located at Robins Air Force Base; it was the only instance prior to the 2009 digital transition in which one of Georgia Public Broadcasting's television stations changed channel frequencies. It was the tenth and last PBS member station established in the state of Georgia, as well as the last television station to be built and signed on by GPB. In the summer of 2006, the station changed its call letters to WMUM-TV, in reference to the Macon-based Mercer University, reflecting the university's involvement in GPB's television and radio operations in the Macon market.
