Greater Nebraska Television sold its stations (including KNOP-TV) to Hoak Media in 2005.
On November 20, 2013, Hoak announced the sale of most of its stations, including KNOP-TV and K11TW, to Gray Television. The sale made them sister stations to North Platte CBS affiliate KNPL-LD, a semi-satellite of Gray's KOLN/KGIN.
After Schurz Communications' stations were bought by Gray Television in 2015, KDUH-TV became a KNOP satellite, and its call letters becoming KNEP for its conversion to a KNOP-TV satellite.
