In May 2013, SagamoreHill Broadcasting reached a deal to sell KGWN and KSTF, along with KGNS-TV in Laredo, Texas, to Yellowstone Holdings, a subsidiary of Frontier Radio Management. On November 4, 2013, Gray Television announced a deal to acquire Yellowstone Holdings for $23 million. That reunited KGWN with many of its former sister stations under Benedek ownership after being separated for 11 years. KGWN-TV was operated under a local marketing agreement by Gray until the closure of the deal, on December 31. On December 19, 2013, KGWN announced that it would close "Northern Colorado 5," citing the inability to make the service "a viable long-term operation."
