KWYB is a full-service television station in Butte, Montana, broadcasting locally in digital on UHF channel 19 as an affiliate of ABC. The station's signal is rebroadcast on KWYB-LD UHF channel 28 in Bozeman. The station is owned by Cowles Publishing Company.
On January 9, 1992, the Federal Communications Commission (FCC) granted an original construction permit to Continental Television Network (CTN) for a full-service station on channel 18 to serve Butte. The station, at first known by its application identification number, 910225KE, soon took the call letters KWYB. The station signed on September 27, 1996.
In February 2001, CTN sold KWYB, along with KWYB-LP in Bozeman, KTMF in Missoula, KTMF-LP in Kalispell and KTGF in Great Falls, to Max Media of Montana. They were the first television station acquisitions in Montana for Max Media.
On September 30, 2013, the Cowles Publishing Company acquired Max Media's Montana television station cluster (which, in addition to KWYB and KTMF, included KFBB-TV in Great Falls, KHBB-LD in Helena, and NBC affiliate KULR-TV in Billings) for $18 million. The sale was completed on November 29.
