In 1955, the station was bought by Des Moines-based Cowles Communications. In 1956, the station boosted its signal to cover all of the Wichita metropolitan area. It also moved its main studio to KEDD's former studio on 37th Street, where the station remains to this day. However, to this day it is still licensed to Hutchinson, identifying as "Hutchinson/Wichita." Along with the power increase, KTVH began broadcasting CBS programming in color, becoming the first station in Wichita to do so. KEDD did not have the capability to broadcast in color. In 1962, the Federal Communications Commission (FCC) collapsed central and western Kansas into the Wichita market. The three CBS affiliates in western Kansas—KTVC (channel 6, now KBSD-DT) in Dodge City; KAYS-TV (channel 7, now KBSH-DT) in Hays; and KLOE-TV (channel 10, now KBSL-DT) in Goodland—became semi-satellites of KTVH. The four stations were known as the Kansas Broadcasting System, with KTVH as the flagship station, relaying CBS programming to what is now one of the largest geographic markets in the nation.
