it into standalone station KYTX, which became a CBS affiliate in April 2004 (the first in the market since KLMG-TV (channel 51, now KFXK-TV) switched to Fox in April 1991). KETK subsequently signed on a low-power translator on UHF channel 53, KLSB-LP (which later changed its call letters to KETK-LP in 2007) to relay its signal to the southern part of the market; the station shut down in 2012. In June 2006, Communications Corporation of America filed for Chapter 11 bankruptcy protection. Rival CBS affiliate KYTX (channel 19) sparked controversy by publicly announcing the ComCorp bankruptcy on its newscasts, for an entire week. ComCorp said in a press release viewers and staff would see no changes at the station. The company emerged from bankruptcy in late 2007. On April 24, 2013, the Communications Corporation of America announced the sale of its television stations, including KETK-TV, to Nexstar Broadcasting Group. KFXK and KTPN were sold to Nexstar partner company Mission Broadcasting; in the case of KFXK, that station was sold to Mission to comply with Federal Communications Commission (FCC) duopoly rules. Nexstar continued KFXK's and KLPN's shared services agreement with sister station KETK. The sale was completed on January 1, 2015. During March 2017, KETK celebrated its 30th anniversary on the air. Nexstar completed a $4 million renovation of KETK's studio and office facilities in November 2017. A dedication and reception was held on November 16, which included the presence of Nexstar chairman/president/CEO Perry Sook, as well as Leslie Roberts, an anchorwoman who worked for KETK in the late 1980s, among other attendees. KLSB-TV station history Prior to KETK-TV's sign-on on March 9, 1987, the Jacksonville-based station intended on providing a signal to both the Tyler–Longview and Lufkin-Nacogdoches areas (Nielsen Media Research designates the two areas as a singular market, although television station signals from Tyler and Longview could not reach Lufkin and vice versa due to the distance between these areas). KETK later moved its main studio facilities from Jacksonville to a new complex in Tyler; in 1991, the station arranged to simulcast its programming in east-central Texas, serving southern portions of the market that could not receive KETK's channel 56 signal, on a newly licensed UHF station in Nacogdoches, KLSB-TV (channel 19), which would be operated by KETK-TV under a local marketing agreement. KLSB-TV signed on the air on September 1, 1991; it ran the majority of the KETK
