Editor's Note: On May 21, David Cook became the latest winner of American Idol, taking the prize by a margin of 12 million votes out of a record 97.5 million cast.

American Idol, which is wrapping up its season finale on May 22, is the most successful television show of this short century. Let that statement sink in for a moment. Yes, the show that gave us Clay Aiken and William Hung and Ryan Seacrest is the pop-cultural phenomenon of the post-9/11 world.

Idol launched in June 2002, and its first episode was watched by a mere 9.9 million viewers. But in time, the numbers would grow significantly—to more than triple that. American Idol is, to today’s iPod-listening and iPhone-yapping adolescents, the equivalent of the Beatles, as painful as that might be for a certain generation to accept. On February 9, 1964, a reported 73 million people watched the Fab Four’s introduction to America on The Ed Sullivan Show—like Idol, a top-rated variety program with some memorable acts and some not-so-memorable acts. That’s one million fewer than the number of votes cast during the season finale of American Idol last year—not bad in an era when there are a zillion channel choices, not the three of Sullivan’s day.
 
Yet in the beginning, plenty of television insiders, including executives at three major networks, ABC, CBS and NBC, all passed on their chance to buy the show. Rupert Murdoch, chairman and C.E.O. of News Corp., the Fox Network’s corporate parent, said yes (though some have said it was actually Mike Darnell, Fox’s reality chief, who gave the go-ahead).  Now, in an era of endless cable stations and diminishing returns for networks, American Idol dominates television, and Murdoch’s News Corp. reaps the financial benefits.

But ratings are down a bit this year, and Idol-haters are predicting the show’s demise. Not Murdoch, of course, who last year said: “I think it’s got years and years of life.” Here’s the tally on Idol to date:
