WRNB

[5] Its effective radiated power was 4,200 watts, simulcasting the Christian programming of its AM sister station 690 WXUR (now WPHE in Phoenixville, Pennsylvania).

In 1981, after a seven-year comparative hearing, the FCC awarded the license to the Greater Media Radio Company, owned by Daniel Lerner.

In the early 1990s, however, the battle for AC listeners heated up, with WEAZ (now WBEB) becoming the dominant station for soft music in Philadelphia.

The flip came three days after Eagle 106 gave up Top 40 and switched to smooth jazz, creating an opening which WKSZ hoped to fill.

[7] New York's WHTZ, located on the same frequency of 100.3 MHz, and calling itself "Z100" since 1983, demanded that WKSZ drop the name to avoid listener confusion.

The station initially had a slight alternative rock lean, but still played other Top 40 hits, including pop and dance.

By early 1995, WPLY evolved into a full-time alternative rock format, which lasted nearly ten years.

On February 24, 2005, at 11:50 pm, WPLY ended its alternative rock format with "Alive" by Pearl Jam (which was also the first and last song on WDRE).

For the next few years, 100.3 The Beat enjoyed high ratings, helped by Miss Jones in the morning and Colby Colb in the afternoon.

In late 2010, WPHI-FM became the Philadelphia home of the Star and Buc Wild Morning Show, syndicated from New York City.

[14][15] WRNB was simulcast on both 100.3 and 107.9 until September 2, when the WPHI call sign moved to 107.9, adopted the former "Beat" format and rebranded as "Hot 107.9."

At that time, after playing "Keep Your Head to the Sky" by Earth, Wind, & Fire, WRNB flipped to urban oldies as "Old School 100.3."

In response, WRNB re-added some current music, although the station continued to focus on older urban hits.
