Title:
American_Broadcasting_Company

Context:
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. ABC has also aired the Miss America pageant from 1954 to 1956, 1997 to 2005 (with the television rights being assumed by cable channel TLC in 2006, when the pageant moved from its longtime homebase in Atlantic City to Las Vegas, before returning to Atlantic City in 2013) and since 2011. Under its current contract with the Miss America Organization, ABC will continue to broadcast the pageant through 2016.
