• But what about the ratings ? As the Daily Mail put it this morning: "You might have thought that the loss of American Idol's most iconic judge would mean the end for the show. Instead it seems that the loss of Simon Cowell could have been Idol's saviour. The resulting injection of fresh opinions in the form of Jennifer Lopez and Steve Tyler has revitalised idol, halting the steady decline in viewers seen for the last four years. It is now drawing in an average of 25 million viewers, matching last year and marking the first time since 2007 that rating haven't fallen."
