When it was initially established as WFIL-TV(the "FIL" was short for "FILadelfia," the Spanish form of the city's name), the station was owned by Triangle Communications, and it was a sister company to the Philadelphia Inquirer.
1947–1948 (as WFIL-TV on both Blue-DuMONT)
1948–1956 (as WFIL-TV on Blue-ABC & DuMONT)
1956–1963 (as WFIL-TV ABC 6)
In 1967, WFIL-TV's logo became standardized. Though the type font style name did not become widely known at the time and still was not widely known as of late 2016, the station would employ this logo for the next four years.
On Wednesday April 27, 1971, WFIL-TV became WPVI-TV after Triangle sold the station to Capital Cities. The back-then station announcer, Paul Norton, reassured viewers, "It's STILL Channel 6."
The change of the station call sign led to a revision of the logo which used the same type font style as previously.
In 1997, The Walt Disney Company absorbed Capital Cities/ABC into itself, giving rise to the Disney-ABC Television Group which still exists at the present time. The station logo design, however, did not immediately reflect this take-over of the station's parent network.
In 2010, WPVI's logo was given an update; while the "6" design remained the same as its has been since it first debuted in 1967, a blue circle with a white outline was added, which made it look more similar to the logos used by most of WPVI's fellow ABC-owned stations. The red ABC Circle logo located on the bottom right of the "6" was changed to the black "ball" version that the network had been using since 2007, and it was also slightly enlarged.
