Neither CBS nor Entercom has been a significant player in talk Syndication. CBS’s niche was “all news” radio stations in major markets like WCBS, WINS, WBBM, KYW, WBZ, KCBS, etc. A long time ago CBS had a relationship with Westwood One, but that was dissolved quite some time ago. CBS experimented with FreeFM for a couple years, but it was entirely an internal syndication.
Radio America is the syndicator for the Dana Loesch show. It is owned by a nonprofit organization whose objective is to give attention to Washington DC politicians about the needs of veterans. They previously had syndicated G Gordon Liddy.
