I was going to disagree because some U.S. remakes of British shows have not been as good or have been terrible, but in-general tried and true products in a market in one country have a better chance of succeeding in another country in similar form. This generalization pretty much carries over into most products and services.
Something else that would be interesting would be to show the # record/CD/mp3 sales of cover songs of successful original vs. originals by the same band doing the cover.
