WOGL (98.1 FM) is a commercial radio station licensed to serve Philadelphia, Pennsylvania, owned by Audacy, Inc.

Beginning the next month the station was issued a series of special authorizations to operate commercially with a temporary antenna, followed by its first full license on March 2, 1943.

[4] William Penn Broadcasting also operated AM station WPEN (now WKDN) in Philadelphia, and on November 1, 1943, W73PH was assigned the WPEN-FM call sign.

[4] On December 4, 1953, the FCC granted WCAU, Inc. a construction permit to relocate the station's transmitter and antenna to the Roxborough section of Philadelphia.

Along with other CBS FM stations, WCAU-FM began airing "The Young Sound," a prerecorded format of instrumental easy listening songs based on contemporary hits.

[6] For prerecorded announcements, the station used the voice of Jim Nettleton, a disc jockey on top-rated WABC in New York City.

The station experimented briefly with a format called "Mellow Rhythm" at this time, hosted primarily by Dr. Perri Johnson (now a music therapist in Los Angeles).

Program consultant Mike Joseph was brought into WCAU-FM in April 1981, to develop a new format to replace the struggling "Mellow Rhythm".

On September 24, 1981, at midnight, the new format at WCAU-FM debuted: an all-current-hits, high-energy, jingle-intensive top 40 sound dubbed "Hot Hits".

WCAU-FM's ratings showed an immediate improvement, and subsequently, FM stations in major radio markets such as WBBM-FM in Chicago, WHYT in Detroit, WMAR-FM in Baltimore, CKOM in Saskatoon, WFEC in Harrisburg, WNVZ in Norfolk, and KITS in San Francisco picked up the "Hot Hits" format.

[7] WCAU-FM found a great deal of success with this programming for much of the mid-1980s, although the original "Fusion" jingles from TM were dropped in the summer of 1982, and replaced with a package from JAM to increase appeal to older listeners.

Some notable DJs on the station in this period included Paul Barsky, Rich Hawkins, Billy Burke, Terry Young and Christy Springfield.

On November 9, 1987, at 7 p.m., after playing "Another One Bites the Dust" by Queen, WCAU-FM returned to the oldies format as WOGL (which stood for "Old Gold").

The station still played artists such as Elvis, The Beatles and The Rolling Stones, but in addition, it focused on soul, including Philadelphia-only hits.

WOGL aired specialty shows such as the "Hot Lunch Special" request show, "The Weeknight Hall Of Fame," "Top 20 Oldies Countdown," "Elvis & Friends," "The Saturday Night Dance Party," "Brunch With The Beatles," and "Street Corner Sunday" (a Doo Wop music program).

With the move, the station temporarily suspended most of their airstaff with the exception of morning host Sean 'Coop' Tabler; Audacy Philadelphia market manager David Yadgaroff disclosed to the Philadelphia Business Journal that the mostly-jockless launch is expected to last, by his estimation, "a short period of time — a couple of weeks to a month or so.
