KSVT signed-on in 1997 as an independent station, K43FK. It became KTWT-LP in 2000. The station was a UPN affiliate from late 2004 (picking up the UPN affiliation from KIDA) until September 2006 when UPN merged with The WB (which was seen on KWTE, via The WB 100+) to form The CW; that network was seen on KTWT (via The CW Plus) until 2012, when it switched to MyNetworkTV following the closure of sister station KTID-LP. CW programming remains available through the second digital subchannel of KMVT, which previously simulcast with KTWT. It had a construction permit for a low-power digital station on Channel 14 although LPTV stations are not required to broadcast digital signals.
