The fourth season of Dancing with the Stars premiered on March 19, 2007 and aired until May 22, 2007. To avoid direct competition with Fox's American Idol, Dancing with the Stars changed time slots from the previous season. In this season, the performance show aired on Mondays, and the results show aired on Tuesdays. No elimination was scheduled for the first week, in order to allow viewers two weeks to see all of the couples perform both Latin and Standard ballroom dances. This season was broadcast on BBC One in the United Kingdom on Sunday afternoons from Sunday, July 15, 2007. Captions appeared on screen throughout the show to remind viewers that this was recorded earlier in the year and that they could not vote on the outcome. None of the first three seasons was screened in the UK. This season beat season two for the highest amount of perfect scores awarded, and fifteen perfect scores were awarded.
