program schedule, with the only differences being local commercials, and in some timeslots, local news inserts. Max Media, a company partially related to former KETK owner Max Media Properties, purchased KLSB-TV in 2003. Upon acquiring the station, Max Media terminated the LMA with the Communications Corporation of America (which bought KETK in 1998) and signed an affiliation agreement with CBS to become the market's first affiliate of that network since KLMG-TV (channel 51, now KFXK-TV) switched to Fox in April 1991. It also leased a building in southeast Tyler that formerly operated as a four-screen movie theater to serve as the station's new studio facilities. That winter, Max filed an application with the FCC to change the station's callsign to KYTX. Channel 19 dropped the KETK simulcast on April 11, 2004, and officially joined CBS the following day on April 12. On April 13, the FCC officially granted the call sign change to KYTX. On June 13, 2004, the station relocated its transmitter facilities farther north of the original transmitter facility to expand its signal to the Tyler and Longview areas, to a new tower located south of New Summerfield. KETK-LP station history After the conversion of channel 19 to CBS, the Nacogdoches–Lufkin portion of the Tyler–Longview television market was left without over-the-air access to NBC programming. KETK then entered into an LMA to lease programming time on a new low-power UHF station on channel 53 in Lufkin, assuming the former full-power station's calls as KLSB-LP. As with KLSB-TV, the station began simulcasting KETK-TV's full schedule, except for local commercials and inserts into KETK's newscasts, with advertising and news aimed at the Lufkin and Nacogdoches area. The station's call sign was changed to KETK-LP on April 13, 2007. On September 1, 2009, KETK-LP's transmitter was shut down. However, its programming remained available in the area via cable on Suddenlink Communications, which also carried NBC programming and KETK news simulcasts from the station in high definition. The station had a construction permit to build digital transmitter facilities, with plans to operate a digital signal on UHF channel 27 under the callsign KETK-LD. The FCC canceled both KETK-LP's license and digital construction permit—its digital transmitter facility was never built—at some point in 2011 or 2012. Programming KETK-TV carries the entire NBC network schedule; however, it delays the network's overnight lineup (consisting of a rebroadcast of the fourth hour of Today and the
