The season finale of Simon Cowell's latest TV talent contest, The X Factor, attracted a record-breaking 44 percent of the British TV audience on Saturday, according to ITV, the commercial TV network that carried it. The contest, won by Leona Lewis of London, an office worker, reportedly delivered 12.6 million viewers, topping the 9.3 million for last season's finale. ITV said that 8 million viewers cast votes by phone. (Lewis's performance was quickly posted on YouTube.com.) The program was reportedly scheduled in such a way as to allow Cowell to resume, after a brief break, his role as a judge on Fox's American Idol next month.
