KETK-TV (channel 56) is a television station licensed to Jacksonville, Texas, United States, serving as the NBC affiliate for East Texas. It is owned by Nexstar Media Group alongside Tyler-licensed low-power MyNetworkTV affiliate KTPN-LD (channel 48); Nexstar also provides certain services to Longview-licensed Fox affiliate KFXK-TV (channel 51) under a shared services agreement (SSA) with White Knight Broadcasting. The stations share studios on Richmond Road (at Loop 323) in Tyler, while KETK-TV's transmitter is located near FM 855 in unincorporated northwestern Cherokee County. KETK-TV was previously relayed on repeater station KETK-LP (UHF analog channel 53) in Nacogdoches. It originally simulcast KETK's entire schedule, but began to produce local news inserts focused on the Nacogdoches–Lufkin area by the late 2000s. KETK-LP's low-power signal only covered the immediate Lufkin area, therefore requiring cable to view the station outside of the city. The station was carried by Consolidated and Suddenlink in Lufkin and Communicomm in Huntington. In recent years, KETK has refrained from identifying its channel number as part of its station IDs, newscasts, or promotions. The station prefers to use just its call letters in those situations. History KETK-TV station history In 1984, the Tyler–Longview area gained its second network affiliate, CBS outlet KLMG-TV. As that occurred, the battle was on to build a third network-affiliated station to bring NBC to East Texas. The first contender in the ring was Sunrise Broadcasting, which merged with a competing applicant for channel 14 in December 1982; East Texas Broadcasting, which was building another station, KTET (channel 60), was described as doing "too much, too soon" with no agreement in hand with the network: it went as far as hiring a news department before it was foreclosed on. However, as other groups sought the NBC nod, it was held the entire time by another permittee: Thomas Robert Gilchrist, who won a construction permit in early 1985 for KTRG (using his initials). Gilchrist went bankrupt, and the construction permit and NBC affiliation agreement were sold to Texas American Broadcasting, in which two of the three partners owned KTEN in Ada, Oklahoma. Texas American proceeded to change the call letters to KETK and begin construction. Even before channel 56 was on the air, TAB was operating a low-power station providing NBC programming to the Jacksonville area. KETK was originally planned to start in February, but equipment delays and high winds led it to be pushed back. Even
