It was a very good Labor Day weekend for BBC America. The September 1 season premiere of Doctor Who and the broadcast of the third episode of the new historical police drama Copper delivered the network its highest rated weekend ever. The return of the eccentric Time Lord brought BBC America its highest-rated, most-watched telecast ever in Live + Same Day. Number one on cable in its 9 PM EDT Saturday time slot, Doctor Who pulled in 1.555 million viewers, with 723,000 among Adults 25-54. The Cineflix-produced Copper, which debuted on August 19 with 1,805,000 viewers, has become BBC America’s highest rated drama ever, with more than a million viewers a week.
