UPDATES STATUS OF CBS NEGOTIATIONS
AND ANNOUNCES EXECUTIVE MANAGEMENT CHANGES

New York, NY — July 12, 2007 — Westwood One, Inc. (NYSE: WON) announced today that it is continuing to work towards execution of definitive documentation regarding the modification and extension through 2017 of its various agreements with CBS Radio. Westwood is optimistic that it will finalize these new arrangements with CBS Radio in August 2007 and submit such documentation to Company stockholders for their approval in the fourth quarter of 2007, following the Company’s filing of a definitive proxy statement with the SEC.

There is no assurance that the extension of Westwood One’s various agreements with CBS Radio will be completed. UBS Investment Bank is continuing to advise the Company’s Strategic Review Committee in its negotiation and documentation of the CBS Radio agreements and the Committee’s mandate to explore avenues to enhance shareholder value.

Westwood One also announced today that it has hired Gary Yusko as Chief Financial Officer, effective July 16, 2007. Mr. Yusko held various positions with the Company from 1985 through 2006, and last actively served as the Company’s Executive Vice President Financial Operations. He replaces Andrew Zaref, who is leaving to pursue other opportunities.

In announcing Mr. Yusko’s appointment, Peter Kosann, President and CEO of Westwood One, said, “We are pleased to have Gary Yusko rejoin Westwood One. As the Company continues to reposition itself in anticipation of its evolving relationship with CBS Radio, Gary’s historical knowledge of our Company and the industry as a former and now current member of senior management will be indispensable. We thank Andrew for his contributions to the Company over the past several years.”

Gary Yusko stated, “I am thrilled to return to Westwood One. I look forward to working with Westwood’s dedicated employees, management and its Board of Directors to improve the Company’s operating performance and increase shareholder value.”

In connection with the anticipated modification of the Company’s agreements with CBS Radio, including the cessation of the Company’s Management Agreement with CBS Radio, the Company announced that Mr. Kosann, a CBS Radio employee, will leave the Company shortly after the completion of the Company’s transaction with CBS Radio, but in any event no earlier than December 31, 2007 and no later than March 18, 2008. The Company will commence a search for a CEO shortly.

The Company also announced that, effective immediately, David Hillman assumes the newly created role of Chief Administrative Officer. In addition to continuing to serve as EVP, Business Affairs and General Counsel, Mr. Hillman will have overall responsibility for the Company’s corporate development and strategic direction and will assist the CEO in overseeing the day-to-day operations of the Company.
