"Idol's" drop among total viewers wasn't as steep: the two-hour broadcast drew 21.6 million, down 18 percent from the Season 10 premiere of 26.25 million. Still, the season 11 kickoff marks the show's lowest-rated season opener since "Idol's" first season premiere, which garnered 9.85 million viewers. The show's highest-rated season premiere came in 2007, when the start of season 6 drew 37.4 million viewers.
