“On June 10, 2013 Apple introduced a peek at iOS 7 and one of the highlighted features was their new iTunes Radio service,” Jack Purcher reports for Patently Apple.

“Today, the US Patent & Trademark Office published a patent application from Apple that reveals that they’ve been seriously working on this project since December 2011 – though there’s evidence dating the project back to at least 2010,” Purcher reports. “Revelations found in our report today cover such matters as dynamic playlists, a user feedback system, an easy drag and drop feature to readjust playlists quickly and more including eight detailed patent figures clarifying many of the noted features.”
