WDCA-TV signed on as an independent station on April 20, 1966; it was originally owned by the Capitol Broadcasting Corporation. Channel 20 was Washington's third independent station, nearly 20 years younger than its future sister station WTTG, which had been founded as a DuMont affiliate, and after WOOK-TV (now defunct, its channel position is now occupied by WFDC-DT), the nation's first African American-oriented television station.
This station's branding is known as "Paramount 20", with the logo design shared with then-sister stations KTXA in Fort Worth-Dallas and KTXH in Houston, both in Texas.
In 2001, Fox Television Stations, traded KBHK (now KBCW) to Viacom in San Francisco-Oakland-San Jose for KTXH in Houston and WDCA in Washington, D.C., thus WDCA became sister stations with Fox O&O WTTG after the buyout of BHC Communications.
Following the announcement of the shut down of UPN (whose programming would be merged with The WB to form The CW), all Fox-owned UPN stations, including WDCA, dropped the UPN name and logo from their on-air branding. WDCA replaced the UPN logo with "DCA", and rebranded the station as "DCA 20", a throwback to the old "DC 20" branding WDCA carried back when it was still an independent station.
With the pending launch of a new Fox-owned network known as MyNetworkTV, WDCA dropped the "DCA" letters and replaced it with the "my" lettering, which would be used in the current logo.
C More My 20, featuring the station's mascot C More. Also used for sister station KTXH.
On July 17, 2017, WDCA was rebranded from "My20" to "Fox 5 Plus", in addition, the station also debuted an 8:00pm newscast produced by WTTG. This rebrand was later carried out by sister station and fellow affiliate WRBW in Orlando, Florida.
