KLBK-TV (channel 13) is a television station in Lubbock, Texas, United States, affiliated with CBS. It is owned by Nexstar Media Group, which provides certain services to ABC affiliate KAMC (channel 28) under a local marketing agreement (LMA) with Mission Broadcasting. The two stations share studios on University Avenue in south Lubbock, where KLBK-TV's transmitter is also located. History The station began its broadcasting operation as KDUB-TV, founded by the late television pioneer W.D. "Dub" Rogers, Jr, putting the station on the air for the very first time on November 13, 1952. It was the first commercially licensed television station in a medium to small-sized market. Over the next few years, Rogers signed on KPAR-TV in Abilene (now KTXS-TV), KEDY-TV in Big Spring (now KCWO-TV) and KVER-TV in Clovis, New Mexico (now KVIH-TV, a satellite of KVII-TV in Amarillo). These stations made up the West Texas Television Network, the first regional television network in the United States. Originally the station also carried ABC as a secondary affiliation until 1969 when KSEL-TV (now KAMC) became the local primary ABC affiliate. The station also carried an affiliation with DuMont during the early 1950s. Grayson Enterprises (named for Sidney Grayson but after 1964 not owned) assumed ownership of KDUB-TV and KPAR-TV in 1961 and changed KDUB's call letters to the current KLBK-TV. The KDUB call sign was later used by KFXB-TV in Dubuque, Iowa, from 1976 to 1995 when it was an ABC affiliate; the station is now owned by the Christian Television Network. Over the years, Grayson acquired several other stations, including KVKM-TV in Monahans (later KMOM and now KWES). However, Grayson Enterprises ran into license renewal trouble in 1968, 1971, 1974, and 1977 for some of its stations. These stations were accused of fraudulent billing, program and transmitter log fabrication, main studio violations, failure to make required technical tests, and other issues. The stations had their renewals deferred and hearings ordered as a result. The case was settled in what was then described as a "distress sale", in which Grayson's stations were broken up and sold to minority-controlled groups (nowadays known as historically-underutilized groups) at a reduced price. The parameters of such a sale were defined by this sell-off. As a result, KMOM and KWAB were transferred to a Hispanic-controlled group, while KLBK and KTXS went to Prima, Inc. (whose principals were African American). The other stations in the West Texas
