The 102.1 MHz frequency in Philadelphia was originally occupied by WFIL-FM. In 1948 it was used to transmit some experimental facsimile broadcasts, presumably related to The Philadelphia Inquirer, which was under common ownership with the radio station. On July 10th, 1968, WFIL-FM switched away from background classical music to an early version of an adult contemporary format. Known as Popular 102, the station featured softer pop music of the day with a mix of currents, oldies and instrumentals. Each hour featured a track from a featured album of the week, and voices on the station were pre-recorded announcements and news from the voices at sister station WFIL-AM, including Jay Cook, J.J. Jeffrey, Tommy Tyler and news by the likes of Allen Stone and Glenn Barton.
