On Friday, CBS Radio's KXNT-FM in Las Vegas launched "The All New Q100.5," playing "Today's Rhythm and All The Best Old School." The previous format was a simulcast of CBS' News-Talk 840-AM. The AM station will continue to broadcast the news and talk programming. Market Manager Tony Perlongo said, "100.5 is a powerhouse signal, and we're excited to feature its own unique sound and music brand. Plus 840 is the premiere frequency on the Las Vegas AM band and is the ideal home as we continue our enduring commitment to providing the region with the best in news and opinion."
