CNN Radio, the cable channel’s digital-only audio news platform, is shutting down effective immediately, according to a CNN press release. Today will be its last day of broadcast, and staff’s final day will be Friday. The decision will affect about 12 staffers, according to the release. The network had been digital-only since April 2012. In February 2011, former Georgia Public Broadcasting News Director Susanna Capelouto left her job to become a producer at CNN Radio.
