On September 15, 2013, Cumulus announced that it had entered into a partnership with music streaming service Rdio; Cumulus took a stake in Rdio, and provided the company with access to its advertising sales team for a freemium tier, the ability to offer Cumulus radio stations on the Rdio service, and $75 million in marketing on Cumulus stations over five years. The stations launched on Rdio in August 2015; prior to the deal, Cumulus partnered with the competing iHeartRadio service. However, in November 2015, Rdio filed for bankruptcy and sold its assets to Pandora Radio.
