Sand Shift: Former iHeartMedia/Panama City-Tallahassee, FL Market President Jackie Rinker has joined Cumulus/Pensacola as VP/MM for the five-station cluster which includes WXBM. She succeeds Davey Wilhoit, who exits after two years. “Jackie is a great addition to our management team," says RVP Pete DeSimone. "We have very talented people in Pensacola and I’m confident Jackie’s leadership will help develop each to help the market reach its full potential.” Rinker's previous stops include iHeartMedia/Birmingham, Cox/New Haven, CT and Cox/Orlando.
