The network was originally founded as
CBS Sports Radio, which was operated by
CBS Radio in partnership with
Westwood One—who handled sales and distribution. The rights to the
CBS logo, but not the name, expired at the end of 2019; the rights to the CBS cross-branding—which had originally been scheduled to expire at the end of 2020, ended on April 15, 2024. At this time, the network rebranded as Infinity Sports Network; the name is a nod to
Infinity Broadcasting Corporation, a corporate predecessor to CBS Radio. On October 21, 2025, Audacy announced that the day-to-day operations of Infinity Sports Network would be taken over by Westwood One, and that the network would rebrand as Westwood One Sports on December 29, 2025. The network introduced a new lineup, including a new morning show hosted by podcaster Drake C. Toll, and new afternoon drive hosts Chris Bleck and Adam Abdalla (formerly of
WMVP Chicago). Programming from Audacy's
BetMGM Network is also being incorporated into the national lineup, including
You Better You Bet and
BetMGM Tonight. ==Stations==
