Cumulus Media Networks was an American radio network owned and operated by Cumulus Media. From 2011 until its merger with Westwood One, it controlled many of the radio assets formerly belonging to the American Broadcasting Company (ABC), which was broken up in 2007; Cumulus owned the portion of the network that was purchased by Citadel Broadcasting that year. The network adopted its final name in September 2011, following Cumulus's acquisition of Citadel; prior to this, it had been known as Citadel Media Networks since April 2009, after licensing the "ABC Radio Networks" name from The Walt Disney Company for nearly two years. ABC now operates a revived ABC Radio Network that owns no stations but produces (mostly short-form) audio content.
