There are a few caveats here. The demographic being compared here is 18-54 year old men, which their advertisers target. WFAN separates the feeds for streaming and terrestrial radio for advertising purposes, whereas ESPN does not. The Michael Kay Show is also on YES Network and SiriusXM, which means that it’s almost certain they have a bigger aggregate audience right now. Nevertheless, if you compare apples-to-apples, Francesa will emerge the winner.
It’s easy to envision a scenario where both sides say they won.
