KLAS first signed on the air on July 8, 1953; the station was originally owned by Las Vegas Television Inc., run by Hank Greenspun, owner of the Las Vegas Sun. Channel 8 was the first television station to sign on in Nevada (beating KOLO-TV in Reno to the air by two months and five days). It has always been a CBS affiliate, but maintained a secondary affiliation with ABC, which it would share with KLRJ/KORK-TV (channel 3, now KSNV-DT) from that station's sign on in January 1955, until KSHO-TV (channel 13, now KTNV-TV) debuted in May 1956. Greenspun sold the station to aviation magnate Howard Hughes's Summa Corporation in 1968, reportedly because the tycoon was dismayed that the station never played his favorite late night movies. After Hughes' death in 1976, the station was held in an outside trust for another two years until 1978, when it was sold to Landmark Communications (Landmark Communications renamed itself to Landmark Media Enterprises in September 2008).
