Westwood One is an American radio network and syndication company specializing in the distribution of talk, music, and sports programming to radio stations across the United States. Founded in 1976 by Norman Pattiz, it emerged as a leader in radio syndication, particularly known for live broadcasts, concert recordings, and satellite distribution of shows. The company grew through acquisitions and went public in 1984, becoming the second-largest producer and distributor of radio programs in the U.S. by the 1990s. It has historically focused on pop-concert programs and leveraged industry contacts to build its network, evolving into a key player in conservative talk radio syndication.

In 2011, Westwood One merged with Dial Global, forming a new entity under the Westwood One name, which was subsequently acquired by Cumulus Media in 2013. Today, as a subsidiary of Cumulus Media, it syndicates prominent programs including conservative talk shows hosted by figures like Mark Levin and Ben Shapiro. The network plays a significant role in the media landscape, particularly in amplifying right-leaning political discourse through radio airwaves. Its operations emphasize partnerships with affiliates and content creators to reach a broad audience of over 2,000 radio stations.

Westwood One's influence extends to sports broadcasting, having held rights to major events like NFL and NCAA games in the past. While it has faced industry shifts toward digital media, it remains a cornerstone of traditional radio syndication, owned and operated within the Cumulus Media portfolio.
