KWBJ-CD

KWBJ originated as a cable-only channel known as ATVC Channel 7, which launched in 1978. It was managed by Allen's TV Cable, owned by Allen Price, which has served the Morgan City area since the 1960s, and it carried local programs and special events for the Morgan City and St. Mary Parish area, before serving as a full-fledged cable channel in April 1986. Among its original programs was a newscast known as Newslook 7. On April 2, 1990, Allen's TV Cable brought the station over the air as K39BJ, broadcasting on UHF channel 39.^[2] Serving Morgan City, Houma, and the southern part of the Baton Rouge market, it originally operated as an independent station. In early 1996, K39BJ became a charter affiliate of The WB Television Network;^[3] in September of that year, the station changed its call letters to KWBJ-LP to reflect its new affiliation. The station began carrying programming from America One as a secondary affiliation in 1999.

On January 24, 2006, CBS Corporation (which split from Viacom in December 2005) and Time Warner's Warner Bros. Entertainment (the division that operated The WB) announced that they would dissolve UPN and The WB, and move some of their programming to a newly created network, The CW.^[4][5] One month later on February 22, 2006, News Corporation announced the launch of a competing "sixth" network called MyNetworkTV, which would be operated by Fox Television Stations and its syndication division Twentieth Television.^[6][7] KWBJ-LP opted against seeking an affiliation with either The CW or MyNetworkTV, instead opting to become a part-time America One affiliate while continuing to carry general entertainment programs interspersed within the network's programming. KWBJ became a YouToo America affiliate once America One folded into that network.

KWBJ's coverage over the air and via cable is limited to St. Mary, lower Assumption, and lower St. Martin parishes; the station is not available over the air or on cable or satellite in the Baton Rouge, New Orleans or Lafayette metro areas. Per its co-ownership with Allen's TV Cable, which provides cable service to the Morgan City area, KWBJ is not carried by any other providers in that area that compete with Allen's TV Cable.^[8]

Since 2017, KWBJ has produced a local current affairs interview program, branded The Voice of the Coast; the half-hour show airs weeknights at 6:30 p.m. and is repeated at 9 p.m. and 8 a.m. the next day. The station also airs local weather updates produced by WeatherVision, during syndicated programming on its evening schedule. Prior to 2017, KWBJ aired a 30-minute newscast. The station also produces South Louisiana Quiz Bowl, an academic competition for area high schools and junior high schools.

KWBJ flash-cut its digital signal into operation on UHF channel 22 in 2009. The station uses its UHF channel 22 as its virtual channel instead of its former UHF analog channel 39 (most, though not all, television stations that maintain digital signals map them to their former analog channel allocations).
