In May 1985, Metromedia sold all of its independent stations (including WNEW-TV) to News Corporation, who announced its intentions to launch the then-new Fox on May 7, 1986, with KTTV, KDAF, KRIV, WFLD, and WTTG forming what would become Fox Television Stations. WNEW-TV became WNYW on March 7.
During this period, WNYW embedded the "5" inside the 'O' in Fox and reintroduced the "5" that was used from 1977 to 1986 under the WNEW callsign and "Metromedia New York 5" branding.
Note: For some reason, this logo is seen on WNYW's official Roku app instead of the current one.
This logo branding, currently in use by most of the Fox O&Os and some Fox affiliates owned by different companies rather than 21st Century Fox is based on the Fox News logo; with their website names ("myfox(city name).com") based off the domain for the social network Myspace, which former Fox parent News Corporation briefly owned.
