The American version of Strictly Come Dancing is showing early signs of becoming a mammoth ratings hit.

Dancing With The Stars made a significant debut last Wednesday, pulling in an average of 13.32 million viewers and ranking as the second most-watched show in the States all week.

Last night's second episode managed to retain - and build - on that initial audience, averaging 14.9 million viewers and a 14% share for ABC.

It easily saw off all its competition, including the premieres of The Inside on FOX (4.7 million) and Psychic Detectives on NBC (6.3 million).
