In November 2017,Entercom assumed operations of the network after it merged with CBS Radio. It continued to manage the network under a licensing agreement with CBS.[8] The rights to theCBS logo, but not the name, expired at the end of 2019;[9] 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 toInfinity Broadcasting Corporation, a corporate predecessor to CBS Radio.[10][11]
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.
