former display format regularly upon the 2009 digital transition). The "O" character also underwent a makeover, acquiring its trademark pillar-like bowl, which has since become a major focal point for the logo and Fox advertising in lieu of the searchlight motif. The "O" is alternately utilized as a zero character in the station logo of several Fox affiliates which have a tens channel location, including Phoenix's channel 10, KSAZ-TV, and Sacramento affiliate KTXL-TV, channel 40. Another revised logo was introduced for the 1995–96 television season, removing the searchlights, but retaining the two lower panes and adding a third pane atop the logotype.

The 1996–99 searchlight logo is still used within the logos of a small number of Fox affiliates; the searchlights continued to be featured in the logo of sister channel FX until a rebranding effort in 2008. The screen bug may have been used from 1999 to 2014; when the network upgraded to high-definition, the watermark placement remained at the 480i format. Until March 14, 2016, they didn't display the on-screen bug, just the hashtag missing the Fox bug, used on some affiliates. For the 2019–20 season, Fox implemented branding elements by Trollbäck + Company, which slightly tweaked the existing wordmark to make it thicker, and introduced an abstract version of the wordmark whose shapes are incorporated into advertising and on-air branding elements (including an
