The station signed on as WCOP on August 26, 1935;[2] owned by the Massachusetts Broadcasting Company, their call letters representing its original studio location at the Copley Plaza Hotel.
In December 1989, the oldies format was replaced by business talk;[7] this gave way in March 1991 to a simulcast of WMJX, and then to leased ethnic programming shortly afterwards.
[8][9][10] WMEX briefly held the WROR callsign in a "parking" move until Greater Media could place the calls on the former WKLB (105.7 FM),[11] then became WNFT on October 17, 1996, as the market's KidStar children's radio network affiliate.
After a period carrying the syndicated "The Touch" urban adult contemporary service, the station became WAMG with a tropical music format on December 1, 1998, adding a simulcast with WLLH in Lowell and Lawrence the following year.
[19][20] In 2003, the station was sold to Salem Communications, and then swapped call letters with 890 AM (which inherited the "Mega" format and the simulcast on WLLH) and became WBPS, which was retained until the sale went through.
Originally, this primarily consisted of hosts from the Salem Radio Network, but in 2006, Paul Harvey News and Comment and The Sean Hannity Show were added to the schedule.
