On March 1, 1948, the station signed on at 98.9 MHz as WSNJ-FM in
Bridgeton, New Jersey, a farming community about south of Philadelphia. It was owned by Eastern States Broadcasting Company. At first, it
simulcast its
sister station,
WSNJ (1240 AM). In the early 1960s, it became an
affiliate of the
WQXR Classical Network, based in New York City. In the 1961, WSNJ-FM's frequency moved to 107.7 MHz, after a frequency swap with the
Philadelphia Bulletins WPBS, and the station resumed simulcasting the
middle of the road format of popular music and news on WSNJ. In 1971, WSNJ-AM-FM were sold to Cohanzick Broadcasting, which held the license until the station's move to the Philadelphia suburbs. In February 2004, the station's frequency and city of license were changed to allow it to move into the more lucrative Philadelphia market. To clear space on the FM band for the new operation, high school station
WHHS was moved from 107.9 to 99.9 MHz and a Philadelphia translator of classical station
WWFM was taken off the air. During transmitter testing, 107.9 used the call sign WPPZ and broadcast
gospel music; owner Radio One eventually gave that call sign and format a permanent home in the market on 103.9 FM. (Before WRNB went on the air in 2004, the call sign was used for a Radio One-owned sister station in Dayton, Ohio, now called
WROU-FM.) The new permanent
urban AC format as WRNB went on the air on February 4, 2005. Radio One paid $35 million for the "move-in" FM station, which was now able to attract Philadelphia listeners and advertisers. On September 1,
2011, Radio One moved WRNB's programming to 100.3, and the
urban contemporary format of WPHI-FM (which moved away from
rhythmic contemporary earlier that year) moved to the weaker signal 107.9 FM as "Hot 107.9" (after stunting that weekend as "
Michael Vick Radio" and "
Rickey Smiley Radio") on September 4 at 5 p.m.. The first song on "Hot" was
Hot In Herre by
Nelly. On November 6, 2014, at 7 p.m., WPHI dropped the "Hot" format and became the fourth classic hip-hop station in the United States (following
KNRJ in
Phoenix,
KDAY/
KDEY in Los Angeles and sister station
KROI in
Houston) as "Boom 107.9". The last song on "Hot" was
I Like It by
Sevyn Streeter, while the first song on "Boom" was
99 Problems by
Jay-Z. On September 27, 2016, at midnight, WPHI and WPPZ swapped formats and call signs with "Boom" moving to 103.9 FM, and the "Praise" gospel format moving to 107.9 FM. (With the change, WPHI's classic hip hop format shifted to
urban contemporary, returning the format to the 103.9 frequency for the first time since 2002 and marking the fourth attempt by Radio One to compete against long dominant
WUSL.) On December 10, 2018, WPPZ flipped to
urban oldies branded as "Classix 107.9"; the "Praise" programming was moved to the HD2 subchannel. ==References==
