 That company, headed by Robert C. Brandon and his brother Ronald, was the licensee of WISR's crosstown competitor, WBUT and WLER-FM, which first signed on the air in 1949.Prior to the sale, WISR had programmed a format of both talk and adult contemporary music.In an effort to make the three stations compete less with each other, Brandon Communications switched the format from adult contemporary to its present one of MOR and easy listening music.
