KSNV, virtual channel 3 and UHF digital channel 22, is the NBC– affiliated television station located in Las Vegas, Nevada, United States. The station's studios are located on Foremaster Lane in Las Vegas (making it the only major television station whose operations are based inside the city limits), and its transmitter is located on Black Mountain, near Henderson (southwest of I-515 / US 93 / US 95).
It was the flagship station of the Intermountain West Communications Company—which was founded by the late James E. Rogers—until the gradual sale of its remaining stations that began in 2013. The Sinclair Broadcast Group, who own Las Vegas's MyNetworkTV and The CW affiliate KVCW (and formerly owned KVMY, now KHSV), had acquired its Reno sister station KRNV-DT and satellite KENV-DT in late-2013, and announced its purchase of KSNV on September 3, 2014. Due to restrictions preventing Sinclair from owning all three stations, the company elected to swap KVMY's license to Intermountain West for that of KSNV. On November 4, 2014, the KSNV call letter, virtual channel number, and intellectual unit moved to the channel 21 license that was previously used for KVMY, effectively putting the station under Sinclair ownership.
