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.
This season featured eleven celebrity contestants. Actor Vincent Pastore was originally announced and partnered with Edyta à Âliwià Âska, but pulled out after one week of rehearsals. He was replaced by John Ratzenberger.
Apolo Anton Ohno and Joey Fatone returned for the All-Stars season, where Fatone was again paired with Kym Johnson and Ohno with Karina Smirnoff.
Tom Bergeron and Samantha Harris returned as co-hosts, while Carrie Ann Inaba, Len Goodman, and Bruno Tonioli returned as judges.
