The station was granted a broadcast license on May 31, 1989, under the call sign W39BC on channel 39, but did not sign on until 1993. WhenCBS affiliateWIVB-TV (channel 4) was granted channel 39 for its digital signal in 1997, W39BC was displaced, but allowed to move to channel 40, and gained the call-sign of WBUF-LP (no relation to the formerWBUF-TV or the currentWBUF-FM). In 1999, it gained the call sign WDTB-LP.
Daystar purchasedWNGS (channel 67) from bankrupt owner,Equity Media Holdings (formerly under alocal marketing agreement (LMA) with and operated byGranite Broadcasting). Because Daystar already had WDTB-LP, it chose to sell the station to ITV of Buffalo, LLC,[2] a partnership owned by local TV personalities Philip Arno and Donald Angelo, for $2,750,000, with plans to program the station fromClarence.[3] As with most sales of its full-power stations, Daystar continues to maintain carriage rights for its network indefinitely on channel 67, and it remains onWBBZ-DT4 as part of the conditions of sale to the present day,de facto operating as its full-market signal in the market.
At the same time, Daystar applied to move WDTB-LP's city of license from Hamburg to Buffalo, and to move to channel 28 afterwards, so it would no longer conflict withCFTO-DT (channel 9). This application was dismissed, though the station was later approved for upgrading to digital operations on UHF 29. The station's digital license was issued on December 5, 2016, with the station changing its call sign to WDTB-LD.
On August 13, 2020, WDTB-LD applied to move from UHF 29 to UHF 18, citing interference fromCKVP-DT (channel 29). As of October 13, 2020, the station wasdark until the channel reassignment was complete.[4] The station was licensed for channel 18 effective October 28, 2022.
On February 8, 2024, Word of God Fellowship surrendered WDTB-LD's license to theFederal Communications Commission; the license was canceled four days later on February 12.
