KCNC-TV
1983–1993
On August 12, 1983, General Electric sold KOA-AM to A. H. Belo, but kept channel 4 and changed its callsign to the current KCNC-TV because of FCC restrictions on different ownership of stations with the same call letters. GE would later acquire NBC's parent RCA in 1986, thus becoming the first owned-and-operated station of a major network in the state of Colorado. The newly-rechristened KCNC-TV continued to use its 1981 circle 4 logo.
1993–2003
1993-1995
This "4" has also been used on NBC's other O&O stations on channel 4 since 1992.
1995–1997
On July 12, 1994, when CBS and Westinghouse Broadcasting agreed to a long-term affiliation deal that would result in three of its stations switch to the network; they initially intended on selling WCAU, but later discovered they would have to pay taxes on the profit of the transaction. To solve this problem, in November 1994, NBC decided to swap ownership of KCNC-TV and KUTV in Salt Lake City (which NBC had acquired the month before), along with the VHF channel 4 allocation and transmitter in Miami, to CBS in exchange for WCAU and the VHF channel 6 allocation and transmitter in Miami, which for legal purposes made the deal an even trade. The affiliation switch took place on September 10, 1995, sending the ABC affiliation to KMGH-TV and the NBC affiliation to KUSA.
1997–2003
Not long after then, in 1997, KCNC was rebranded as simply News 4, with the color scheme changed.
2003–present
The eyemark was reintroduced in 2003 and the NBC-era "4" was phased out by this time, the logo is based on the current one from sister station KCBS-TV in Los Angeles.
