In 1996, the station signed on the air as WAAE. It was owned by Centennial Broadcasting of Florida with studios on 43rd Street in Vero Beach. Within months, it had switched its call sign to WOSN, representing the word "Ocean."[3] The station originally had an adult standards sound. WOSN derived some of its programming from Westwood One's America's Best Music satellite service.
Jeff Rollins, who had been with America's Best Music, hosted a local morning show from 6 a.m. to noon. Weekend programming included Herb Oscar Anderson, formerly of WABC in New York City, Saturdays at 7 p.m.
In early 2017, WOSN updated its sound to soft adult contemporary music.[4] Current on-air personalities include Hamp Elliott, Bob Soos, Jim Davis, Rick Lane, Juan O'Reilly, and Bill Dake (host of the Sunday Smooth Jazz Brunch).[5]
