Public license information: Profile

KNBN, channel 21, is the NBC affiliate in Rapid City, South Dakota. It is owned by Rapid Broadcasting, and is also the sister station to KWBH-LP. KNBN's transmitter is located in Rapid City.

KNBN can also be seen on translators KKRA-LP on UHF channel 24 and K40GS-D on UHF channel 40; both stations are licensed in Rapid City, though K40GS-D mainly serves Lead and the Black Hills region.


The station signed on the air on May 14, 2000. Despite transmitting its signal on UHF channel 21, KNBN identifies as NewsCenter1 on-air, an artifact of when the main cable systems in the market carried the station on Channel 1, which is usually used solely to provide a slot for video on demand services, barker channels or electronic program guide services. Currently, KNBN is carried on local cable systems on channel 10, though it retains the NewsCenter1 branding. Before KNBN signed on, NBC was provided via cable from KUSA in Denver- before that, KEVN served as the primary NBC station in the area.

Digital channels[edit]

The station's digital signal is multiplexed:

Channel Video Aspect PSIP Short Name Programming[1]
21.1 1080i 16:9 KNBN-NBC Main KNBN programming / NBC
21.2 720p KNBN-CW Simulcast of KWBH-LP
21.3 480i 4:3 KNBN-MYNET MyNetworkTV (cable-only)

Analog-to-digital conversion[edit]

Because it was granted an original construction permit after the FCC finalized the DTV allotment plan on April 21, 1997, the station did not receive a companion channel for a digital television station. Instead, KNBN turned off its analog signal and turned on its digital signal on the same channel (called a "flash-cut").

KNBN flash-cut to digital on February 1, 2009 to televise the 2009 Super Bowl in high-definition.[2]
