With ABC's Dancing With The Stars out of the picture, CBS has returned to the top spot in the Monday-night ratings. The network this week won five of the six half-hours of primetime among overall viewers and all of the half-hours among adults 18-49. Meanwhile, ABC's Dancing replacement, Skating with the Stars , has turned into an embarrassment for the network. While Dancing was regularly attracting around 20 million viewers, Skating has slipped to just 4.8 million viewers, placing last among all viewers and the 18-49 demo.
