KCNC-TV, virtual channel 4, is a CBS owned-and-operated station television station in Denver, Colorado, owned by CBS Television Stations, Inc. KCNC broadcasts on UHF channel 35 from Lookout Mountain near Golden, Colorado.

On June 12, 2009, KCNC-TV left channel 4 and continued broadcasting on channel 35 to complete its analog to digital conversion. However, through the use of PSIP, digital television receivers display KCNC-TV's virtual channel as "4".

The station first went on the air on December 24, 1953 as KOA-TV, co-owned with KOA radio (AM 850 and FM 103.5, now KRFX). It immediately took the NBC affiliation away from KBTV (channel 9, now KUSA-TV), due to KOA's NBC radio affiliation. It was owned by Metropolitan Broadcasting, a company partly owned by famed comedian Bob Hope.

In 1965, KOA-TV carried most of NBC's American Football League games with Curt Gowdy doing play-by-play, but Denver Broncos home games had to be blacked out because none of them sold out. In 1967, KOA-TV aired an award winning documentary, The Acid Test, LSD. Five months in the making, with more than 5,000 feet of film shot, LSD was hosted by news editor Bob Palmer. Photographers involved included Bill Baker, Medill Barnes, Jerry Curran, Sam Houston and Barry Trader.

Benjamin Wayne Petrick (born April 7, 1977) is a former Major League Baseball player.

Petrick, who was born in Salem, Oregon, was a highly accomplished athlete while attending Glencoe High School in Hillsboro, Oregon. He was recruited heavily to play both football and baseball, and ended up going straight into the Colorado Rockies' farm system when they drafted him in the second round (38th overall) of the 1995 amateur entry draft. Petrick became a solid prospect, finding a great deal of success with the Rockies' AAA affiliate, the Colorado Springs Sky Sox. He was called up to the Rockies for the first time in 1999 and hit .323 with 4 home runs in only 62 at-bats. In 2000, he hit .322 in 52 games for the major league club. However, he soon experienced a dramatic dropoff in production, hitting only .238 in 85 games in 2001. On July 13, 2003, Petrick was acquired by the Detroit Tigers from Colorado in exchange for pitcher Adam Bernero. After an unsuccessful stint with the Tigers, Petrick was released. He attempted a brief comeback with the AAA Portland Beavers, and then retired.
