KFOR-TV

1949–195?
KFOR-TV signed on the air as Oklahoma's first television station on June 6, 1949, under the callsign WKY-TV.

1976–1979


In 1976, following original owner Gaylord Broadcasting (a subsidiary of the Oklahoma Publishing Company, formerly known as the WKY Television System) sold the station to the Evening News Association, WKY-TV changed its callsign to KTVY.

1990–1994


In 1990, KTVY changed its callsign to the current KFOR-TV; it branded itself as "4 Strong" for entertainment purposes, and as NewsTeam 4 for its newscasts, though the general and news brandings changed to the current NewsChannel 4 in 1993, near the end of the "4 Strong" era.

2008–present


This updated version of the 1997 logo was introduced on August 8, 2008, coinciding with the start of NBC's coverage of the 2008 Summer Olympics in Beijing, China; the "4" logo's color was changed from yellow to blue in this revamp.
