Westwood One American Country Countdown host Kix Brooks is stepping down at the end of the year, with Cumulus KPLX/Dallas morning host Ryan Fox taking over in 2025. Brooks has hosted the show for 18 years; his final show will air the weekend of Dec. 28-29. "It’s time to turn my primary focus back to writing, recording and touring with Brooks & Dunn," says Brooks. "It’s been an honor, to say the least, that I was trusted with a microphone that had such an iconic history. Special thanks to all the fans who listened and participated, to ensure that I was being the best that I could be." American Country Countdown with Ryan Fox debuts the weekend of Jan. 4-5. The show currently has more than 300 affiliates.
