This month marks the 30th anniversary of the iHeartRadio Jingle Ball, which was originally founded on December 15, 1995. For three decades, some of the top performers in Pop, rock, hip hop, R&B and more have gathered in Southern California for the Jingle Ball holiday concerts. Since 2012, the event has been held in multiple cities and has even gone on tour. It's now a Christmas tradition for music lovers in the United States.
