Strictly, which is in its 11th season here, kicked off its live episodes Saturday, drawing an average audience of 9.1 million viewers. That marked the show's highest-rated start of its live episodes in years and was up nearly 400,000 viewers from last year.

Meanwhile, Simon Cowell's X Factor dropped about a million viewers from last week amid Strictly's return, even though the shows only overlapped for 5 minutes. ITV had pushed the start time from 8 p.m. to 8:20 p.m.

An average of 7.8 million watched X Factor, the smallest average audience of the current 10th season. But the show has seen stronger ratings this season up until Saturday. Across its auditions episodes, its ratings were up 7 percent over the 2012 season.

In terms of Saturday peak audiences, Strictly reached 10.16 million viewers, while the X Factor drew 8.83 million. The first time both shows had aired on the same day this season, X Factor had won the peak ratings showdown.

Meanwhile, new BBC drama Atlantis had a good debut Saturday, averaging 5.8 million viewers on BBC One. That meant a share of 26.2 percent of people watching TV in Britain at the time.
