Dial Global began exhibiting signs of financial distress in late 2012, a possible side effect of its numerous acquisitions.

[3][4] On September 4, 2013, ahead of the completion of the purchase, Dial Global announced that it would rename itself Westwood One, citing stronger name recognition.

Among the numerous other holdings Cumulus now controls are the libraries of Transtar, RKO, Waitt, Jones, BPI, Watermark, and Drake-Chenault.

The company's numerous acquisitions prompted rival Talk Radio Network to file an antitrust lawsuit against what was then Dial Global in August 2012.

The merger resulted in layoffs from its Westwood One's facilities in Colorado, including some of its in-house airstaff (who would be offered vacant positions at Cumulus stations).

The company stated that it planned to leverage talent from Cumulus's local stations (particularly in major markets) for its 24-hour formats.

Triton Media Group, by this point rebranded as Triton Digital, was spun off to The E. W. Scripps Company in October 2018; as Scripps does not operate radio stations (it had a brief foray in the medium after its acquisition of Journal Media Group, but divested its stations in 2018), the radio-related assets remain in the possession of Westwood One.
