The three satellite stations clear all network and syndicated programming as provided through KXMB but air separate legal identifications and commercial inserts.

KXMB first went on the air on November 19, 1955, as KBMB-TV, owned by Fargo businessman John Boler and his North Dakota Broadcasting Company.

KXJB-TV in Fargo was co-owned with the KX stations (though programmed separately) until Boler sold his interest in the partnership to Reiten in 1971.

Reiten Broadcasting purchased KNDX (previously KDIX-TV) in Dickinson in 1985 and converted it into a full-time semi-satellite of KXMB and changed the call letters to KXMA (It would have been KXME, but Prairie Public Television objected.)

After an ice storm on April 6, 1997, caused the KXJB-TV mast to collapse, some cable systems replaced KXJB with KXMB, either temporarily or permanently, to maintain CBS service.

A consequence of this agreement has enabled KBMY-DT to begin broadcasting in July 2008 directly from KXMB's station, bringing a digital ABC television signal to Bismarck.

In October 2007, KXNet.com along with Midkota Solutions launched DakotaPolitics.com, a web site focusing on North Dakota political news coverage.

In 2008, KXNet.com became the first web site in North Dakota to deliver a live news broadcast over the Internet when they streamed a 1-hour special coverage of the 2008 Presidential Caucuses from Bismarck.

Nexstar Broadcasting Group announced its $44 million purchase of the Reiten Television stations, including KXMB-TV, on September 17, 2015.

On November 30, 2013, actor Will Ferrell, as a promotion for his film Anchorman 2, co-anchored the station's evening news as his character Ron Burgundy.

[10][11][12] To reach viewers throughout the vast Minot/Bismarck/Dickinson/Williston television market, KXMB extends its over-the-air coverage area through a network of three full-power stations encompassing much of the western and central two-thirds of North Dakota and parts of eastern Montana and northwestern South Dakota, branded as KX Television.

However, their full-power licenses allow them to broadcast separate station identifications and local commercial inserts, as well as different programming if desired.
