Beginning in 1978, several applications were made for what was originally channel 48 in Galveston. Proposals were made by the Old Time Religion Hour (OTRH), Alden Communications of Texas, and Bluebonnet Television, a local consortium that included the former general manager of
KDOG-TV in Houston as well as two Hispanic principals. However, after the FCC decided to grant the permit to Bluebonnet in 1983, OTRH and Alden jointly lodged an appeal. The primary issue that had cost them the permit was twofold. A television studio had been donated to the group, which aired the program of the same name, in
Friendswood, near Houston, and FCC administrative law judge Joseph P. Gonzalez found that OTRH had failed to show good cause for the station's main studio to not be located in Galveston. After the FCC reaffirmed the award of the construction permit to Bluebonnet in 1987, KTMD began broadcasting on February 1, 1988, as a Telemundo affiliate. Broadcasting from the former tower of
KUHT, the station was the second new full-power Spanish-language outlet in Houston, as
KXLN-TV had begun the year before. The original studios were located on Stoney Brook in Houston, with further offices in Galveston staffed by two full-time employees. Telemundo had become a minority investor in Bluebonnet and purchased the remainder of the station that April. In addition to its Hispanic programming, KTMD in its early years brokered two hours a week to the publisher of the
Southern Chinese Daily newspaper to air programs in Chinese. It also produced a variety of local programs, including the weekly talk show (Our People), the Galveston affairs program , and a weekly Catholic Mass. In 2002, KTMD was granted permission to move its analog signal to channel 47 in order to operate its digital signal on channel 48, which would operate from a transmitter located in Missouri City rather than Friendswood. The station also cited interference from a station in
Bryan for its reasoning to change its channel allocation. KTMD officially moved from channel 48 to channel 47 on November 9, 2002. In 2005, KTMD moved to new studio facilities. KXLN remained the dominant Spanish-language station for some time, in news, ratings, and revenue, after KTMD signed on. In 2004, estimates showed that KXLN received $37.8 million in revenue compared to $9.8 million at KTMD, and there continues to be a large gap in news ratings between KXLN and KTMD. ==News operation==
