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. It was also (as ABC Radio Networks) the penultimate of the major radio networks to still be owned by its original founding company until 2007, CBS Radio being the last. Mutual Broadcasting Network was dissolved in 1999, and then NBC Radio Network, after selling all of its stations in 1988, followed suit in 2004. Prominent hosts carried by Cumulus Media Networks included Don Imus, Geraldo Rivera, Mike Huckabee, Mark Levin, Michael Savage, Jim Brickman, Adam Bomb, Kix Brooks (American Country Countdown), and Tom Kent. History Cumulus Media Networks had its origins in an early network set up by WJZ (now WABC) in New York City which provided programs to other stations over Western Union lines. WJZ/NBC Blue Network WJZ (which is not related to the Baltimore TV station that currently uses those call letters), originally owned by Westinghouse and its informal network were absorbed into the National Broadcasting Company in 1927. To the parent company Radio Corporation of America, WJZ and affiliates were known as the Blue Network while New York station WEAF (later WNBC and now WFAN) and its affiliates (also absorbed into NBC) were known as the "Red Network." On the air, both were identified as "NBC, the National Broadcasting Company;" the distinctions between the two networks were, beyond staff and advertisers, mostly a matter of the more popular and established programming appearing on NBC Red. Both NBC networks were owned by RCA; following a Federal Communications Commission investigation into the network's influence over advertising, strict ownership rules were introduced in 1941. RCA was compelled to sell one network and three local stations. ABC Radio RCA put an asking price of $8 million on the Blue network; after
