"Christmas Bells" is an American television commercial produced by the Hershey Company promoting Hershey's Kisses. The advertisement, originally produced with stop-motion animation and later being redone with CGI animation, features Hershey's Kisses, fashioned as a handbell choir, playing the Christmas carol "We Wish You a Merry Christmas". It debuted in December 1989 and is shown in the United States each holiday season; as such, it is the longest-running television commercial for the Hershey brand. In 2012, the ad was redone with a new recording of the audio and the graphics being redone entirely in CGI animation. Since then, that version has been the version playing each year.
