Idol is getting pretty long in the tooth. The show badly misses Simon Cowell. Last year Idol generated fully a third of CKX's revenue -- $91 million of $273 million, according to financial statements. Idol revenue -- including show revenue, tours and merchandising, did grow from $79 million in 2009. Presumably margins will be higher for 2011 now that Cowell's huge salary is no longer on the books.
