Season four of Dancing with the Stars premiered on March 19, 2007, on the ABC network. To avoid direct competition with Fox's American Idol, Dancing with the Stars changed time slots from the previous season. This season, the performance show aired on Mondays and the results show aired on Tuesdays. No elimination took place the first week in order to allow viewers two weeks to see all of the couples perform both Latin and ballroom dances. This season was broadcast on BBC One in the United Kingdom on Sunday afternoons. On May 22, Olympic short-track speed skater Apolo Anton Ohno and Julianne Hough were crowned the champions, while NSYNC singer Joey Fatone and Kym Johnson finished in second place, and boxer Laila Ali and Maksim Chmerkovskiy finished third.
