Although granted a construction permit sometime in 1982 under the callsign W07BM, WPBM did not go on the air until 1998 as W48BM. The station first broadcast on UHF analog channel 48 for the first two years on the air, then moved to channel 31 in 2001 as WPBM-LP, as part of the digital television conversion. Since then, the station was branded as TV 31, Proclaim Broadcasting. WPBM discontinued its analog signal and converted to digital broadcasting in December 2009 on channel 46, but it is displayed as channel 31.1 through the use of PSIP. The current WPBM-CDcall letters were adopted on June 25, 2010. In October, 2019, WPBM began broadcasting on Channel 15, as required by the FCC. WPBM-CD is owned by Scottsville businessman and minister Marvey B. Wood and his late wife, Frances. They are the sole owners of the station, doing business as Proclaim Broadcasting, Inc. Currently, in terms of religious television outlets, WPBM is the only locally based religious television station for the Bowling Greenmedia market of any part, even though Allen County, Kentucky, where the station is based in, is considered to be in the Nashville, Tennessee media market. That is due in part of Allen County's close proximity to the Kentucky-Tennessee state line. WPBM serves at least nearby portions of both the Nashville and Bowling Green media market on both sides of the state line. Hendersonville, Tennessee-based WPGD-TV, an owned-and-operated station of the Trinity Broadcasting Network, also serves parts of southern Kentucky as the default over-the-air TBN affiliate for the area, but is a second option for religious programming. Bowling Green would not be served over-the-air by another locally based religious station besides WPBM until the Sonlife Broadcasting Network became available via the fourth digital subchannel of Antenna TV/MyNetworkTV affiliate WCZU-LD in August 2016.

Analog-to-digital television transition
WPBM was not obligated to transition to digital in the digital television transition of 2009 since it was a low-powered station. September 2015 was the deadline for low-powered stations to transition to digital. In spite of this, WPBM discontinued its analog signal and converted to digital broadcasting in December 2009 on UHF digital channel 46, but it is displayed as channel 31 through the use of PSIP.
As a Christian television station, WPBM produces more than 12 hours per week of local programming, including music, interviews, preaching, teaching and family living shows. Local programming produced by the station includes From the Heart with Frances Wood, Sneed Family Music starring The Sneed Family of Glasgow, Take The Living Word to a Dying World with station owner Marvey B. Wood, and a few other locally produced programs are featured. WPBM airs Sunday worship services on a delayed basis from Shepherd's House in Glasgow, Bethlehem Baptist Church in Greensburg, Abounding Grace Ministries in Scottsville and First Baptist Church, Bowling Green.
