text1: Who succeeded Dick Clark on ABC's New Year's broadcasts?
text2: Since 1974, ABC has generally aired Dick Clark's New Year's Rockin' Eve on New Year's Eve (hosted first by its creator Dick Clark, and later by his successor Ryan Seacrest); the only exception was in 1999, when ABC put it on a one-year hiatus to provide coverage of the international millennium festivities, though Clark's traditional countdown from Times Square was still featured within the coverage.
