Dancing With The Stars' final performance show Monday night also produced its best ratings for the season. The 90-minute telecast averaged 20.49 million viewers, peaking in the final half-hour at 9 00 p.m. with 21.93 million. Tonight's results show is likely to draw even greater numbers, particularly given the fact that Donny Osmond, who is favored to win, has always managed to attract viewers. CBS took over first place at 9 30 p.m. with The Big Bang Theory , which continues to improve in the ratings (and, critics say, in the quality of its scripts). Monday's episode drew $14.22 million viewers. It was followed by CSI Miami, which recorded 13.18 million viewers.
