On March 19, 1984, KBTV became KUSA. The "9" in KUSA's logo is still being used today, and has been the only logo the station has used under that callsign. This is also shared with sister station WUSA in Washington, D.C.; the design is similar to the one formerly used by KMSP-TV in Minneapolis from 1972.
1984–1995 (primary) / 1995–present (secondary)
This logo was used from 1984 (when KUSA was ABC) until 1995 when KUSA became affiliated with NBC. It's barely used today.
KMGH-TV's owner, McGraw-Hill (now S&P Global) had an affiliation deal with ABC and KCNC-TV was traded to CBS. So it made KUSA switch from ABC to NBC. The ABC affiliation moved to channel 7.
Used for the first month as an NBC affiliate after the switch.
The variant that placed the NBC logo to the left of the main logo was dropped as its primary logo after one month but remained in use as a secondary logo until 1999.
In 2005, KUSA gained a sister station when Gannett Broadcasting purchased KTVD, currently a MyNetworkTV affiliate
