KBMY (channel 17) is a television station in Bismarck, North Dakota, United States, affiliated with ABC and MyNetworkTV.

KMCY simulcasts all network and syndicated programming as provided through KBMY but airs separate local commercial inserts and legal identifications.

From the 1970s onward, some cable subscribers in western North Dakota received the full ABC schedule from KULR-TV (now NBC) from Billings, KFBB-TV from Great Falls, KOTA-TV from Rapid City or KUSA in Denver.

By the early 1980s, cable television—a must for acceptable television in much of this vast market—had gained enough penetration for a network affiliate on the UHF band to be viable.

In the early 2000s, KBMY signed on two low-powered translators to serve the smaller cities in the market, K44HR in Williston and K42FY in Dickinson.

From 2002 until 2008, KBMY/KMCY was operated by Prime Cities Broadcasting, owner of western North Dakota's Fox affiliate, KNDX/KXND, in a local marketing agreement.

The LMA with KNDX/KXND ended in 2008, with Forum opting to partner with Reiten Television in KBMY/KMCY's local operations via a joint sales agreement.

While some local advertising staffers were based at KXMB-TV in Bismarck and KXMC-TV in Minot, most operations have been consolidated at WDAY-TV's studios in Fargo.

Under this arrangement, KBMY and KMCY's programming was transported from WDAY-TV's studios to Bismarck via leased microwave relay bandwidth furnished by Prairie Public Broadcasting's statewide digital terrestrial microwave network (the only permanent full-time video link from Fargo to Bismarck for television broadcasting).

WDAY X (as WDAY Xtra) became available in HD in 2014, and in 2016, MyNetworkTV programming began airing (in prime time), although on KBMY and KMCY only (in Bismarck and Minot respectively) but not on WDAY-TV in Fargo or WDAZ-TV in Devils Lake–Grand Forks (the most likely reason being that both of those stations broadcast to a viewing area that is currently being serviced by MyNetworkTV affiliate KRDK-TV from Valley City–Fargo).

When KBMY/KMCY signed on in 1985, the stations originated and aired a local newscast at 10 p.m. with on-location ENG and studio news coverage for the Bismarck and Minot areas.

Forum shelved this first attempt at a local newscast in March 1989 due to concerns about costs; a new reporter was to have moved from California before the shutdown.
