XHBJ's concession history began in the late 1960s with the initial award of the television station to Canales de Televisión Populares, a subsidiary of Telesistema Mexicano (today's Televisa). However, two parties objected to the concession award, which was announced in the summer of 1969: Tijuana FM, S.A., headed by Clemente Serna Alvear, and Mario Enrique Mayans Concha, founder of Cadena Baja California (now Grupo Cadena). In June 1971, the case was heard by the Secretariat of Communications and Transportation, and in January 1988, the SCT finally selected one of the objecting parties to become the concessionaire: Mayans Concha.

The concession was awarded on November 30, 1988, and Mayans set out to build Tijuana's third TV station and second UHF, after XHAS came to air in 1981. Transmitter tests began in the summer of 1989 and the station was on air by 1990, with a schedule of music videos and some local programs including, in 1991, 25 San Diego Padres road games in Spanish^[3] and adding Spanish play-by-play to ESPN and TNT telecasts of NFL preseason contests.^[4] The music video programming, an outgrowth of sister XHMORE-FM 98.9, came to dominate the station's output, and channel 45 was known as "MORE TV" during the 1990s.

Channel 45 began also adding blocks of programming to Galavisión, eventually becoming a Televisa local partner that exclusively rebroadcast network programming.^[5] From 2004 to early 2012, it carried the Canal 5 network, but in early 2012, Galavisión programming returned to XHBJ-TV, with Canal 5 moving to XETV, where it was broadcast on analog channel 6 and digital channel 6.2.

XHBJ lost Nu9ve—the renamed Galavisión—on November 1, 2019, to a subchannel of XETV. The station then rebranded as "45 TV Tijuana" and began airing mostly programming from Multimedios Televisión, along with the local morning and late evening newscasts of Canal 66 of Mexicali, and a simulcast of the program ¨En la Morening¨ from its sister station XHMORE-FM on Fridays.^[6] The IFT would then approve the addition of Canal 66 as a subchannel to XHBJ-TDT on December 2, 2020, though this was never used and expired.

XHBJ currently is authorized to carry one subchannel.
