Forty years ago, Dick Clark's New Year's Eve special was created as an alternative to a seasonal institution, bandleader Guy Lombardo. Now Clark's annual show is the institution. "New Year's Rockin' Eve," with Clark and Ryan Seacrest, pays tribute to its own history during a sprawling, six-hour program Saturday night with performances by Lady Gaga, Justin Bieber, Pitbull, Hot Chelle Rae, Florence + The Machine, Gym Class Heroes and Nicki Minaj.
