“The iHeartRadio Jingle Ball Tour has become synonymous with the holidays,” said Tom Poleman, President of National Programming Group, iHeartMedia. “If you’re an artist who makes it to this stage, it means you’re one of the most important artists in pop music this year.”

"What started as a local holiday concert in New York over twenty years ago, has become a nationwide holiday music tour, a radio broadcast and CW Network telecast that reaches millions of music fans.” Said John Sykes, President of Entertainment Enterprises at iHeartMedia.

Pro tip: If you'd like to attend all stops of the tour, we strongly recommend traveling by Pittman's jet.
