Sean's Key Diddy: Entercom/Sacramento VP/MM Sean Shannon will join Cumulus/Atlanta as MM next week, with responsibilities that include oversight of Country WKHX. Shannon replaces John Pinch, who is retiring after a few months in the role. Pinch served as co-COO for the company until that position was eliminated as part of a leadership restructuring in September (Breaking News 9/4). He was set to retire shortly thereafter, but stayed on in his current role instead (CAT 9/30). "Once again, I'm retiring, and this time it's for real!" Pinch said in a note to staff. "I've truly enjoyed that last five months and the chance to get to know you and the fabulous stations in our Atlanta cluster ... I met Sean seven months ago and the timing was right for this move to happen now." Reach Pinch here.
