KTUD-CD, virtual channel 25.1 (digital channel 20), was an independent television station that served the Las Vegas, Nevada market owned and operated by Greenspun Broadcasting, a wholly owned subsidiary of The Greenspun Corporation. The station went dark and not broadcasting as of the evening of October 10, 2013 and is now defunct.
Unlike other low-powered television stations not connected to a full-power mother station, the station was available on channel 14 through Cox cable systems in the Las Vegas Valley.
The "-CD" suffix in the call letters denoted the station's status as a " Class A" digital television station, a slight upgrade from its previous " low power" (-LD) designation. The station's transmitter was located atop Mount Arden, 6 miles south of Henderson. Its studios and offices were located in unincorporated Paradise Valley, south of McCarran International Airport.
