20th century

The station was originally paired with WRKN 970 AM in Brandon, Mississippi, with the call letters WRJH (initially standing for Roy and June Harris, who were the original owners). Both stations were promoted as "Gospel 97" for many decades. The callsign also came to mean other things as well (We're Raising Jesus Higher). After Harris died, his wife sold the station to On Top Communications, which purchased it for $1.6 million.

The WRJH callsign took on a different meaning ("We aRe Jackson's Hot 97.7). At approximately the same time, On Top Communications, was in the process of acquiring several other stations, including Urban/Hip Hop stations in New Orleans, Albany, Georgia and Norfolk. When On Top went bankrupt in 2005, most of its stations either switched formats or went silent (as the case with New Orleans due to Hurricane Katrina).

A short time later, WRJH was sold at a bankruptcy auction. That was when Roberts Broadcasting bought WRJH for $1,950,000.00, eventually moved its studios into TV station WRBJ's and changed the callsign to WRBJ.^[1]

WRBJ's playlist mainly consists of Hip Hop and R&B. Unlike most stations, this one plays smoother music during the workday timeframe while it plays newer music later afternoons into the early evening, thus positioning WRBJ well with its competitors WJMI, WJDX-FM, WRTM-FM and WKXI-FM.

The WRBJ call letters were previously assigned to AM 1580 and FM 92.1 in Saint Johns, Michigan, from the mid-1960s until August 1981. The original WRBJ-AM-FM was owned by Ditmer Broadcasting, which was headed by Robert D. Ditmer.

21st century

In response to the Don Imus controversy, WRBJ's owner, Roberts Broadcasting, took a stand on excessively violent and derogatory hip hop lyrical content. Jesse Jackson and Al Sharpton have long taken a stand against, and hip-hop mogul Russell Simmons began to stand up against it, calling on people to accept social responsibility.

In April 2007, inspired by the move, Roberts Broadcasting, after reviewing playlists for content, decided to create a policy to ban the station from playing music that glorifies violence and degrades women. The purpose was to take a stand against racism, self-racism with Blacks using the N-word against each other, and promote pride in the African American community by fighting against the oppressive media.^[2][3] While the revamping of the playlist may not be noticeable to listeners, the owner said that any songs on WRBJ-FM containing content considered offensive (other than censored language) will be removed. And it may go on to drop syndication rights to the Russ Parr Morning Show as well, claiming that the morning jock is a borderline shock jock.^[4] This was the first time a radio station owner had done this since Clear Channel banned certain songs from airplay in response to September 11 terrorist attacks.

On March 17, 2008, WRBJ-FM rebranded the station as 97-7 (WRBJ), and began playing fewer hip-hop songs and more R&B music. Russ Parr's morning show has been replaced by that of Rickey Smiley. Upcoming changes for WRBJ-FM include several hours' worth of urban gospel every Sunday, a public affairs program and neo-soul. From September 2008 to April 2013, WRBJ was Jackson's affiliate of Michael Baisden in the afternoons; as of August 2013 it now airs the D.L. Hughley show in Baisden's former slot.
