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 on UHF channel 40; both stations are licensed in Rapid City, though K40GS 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 or NBC1 on air. This is because they used to broadcast on cable channel 1 on the converter box issued by the cable company. KNBN now is carried on the local cable systems on channel 10. 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 television

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.[1]

The CW affiliate KWBH-LP is carried on a digital subchannel of KNBN (channel 21.2 PSIP). MyNetworkTV and RTN is on a third subchannel (channel 21.3 PSIP); this was also aired on KKRA-LP before it switched to KNBN's main NBC programming in 2009.
