Even before Mary Berner starts her first day on the job as CEO, the rumors are flying about possible changes. The rumor circulating yesterday that Berner plans to shut down Cumulus' national Country format NASH is not true, according to sources we spoke to inside the company. Competitors of Cumulus were quick to circulate the rumor as well, hoping to kick the company while it's down. One of the first things Berner plans to do as CEO next week is visit Nashville and hold a town hall meeting at the NASH Campus. An insider told us Cumulus is "very committed to NASH and has plans to continue to grow it."
