A staggering 37.3 million Americans tuned in to watch the sixth season premiere of hit talent show American Idol on Tuesday night (17JAN07). The figures, two million more than last year's (06) season debut, gave the show its second highest-rated telecast ever. Only Clay Aiken and Ruben Studdard's final sing-off in May, 2003, brought American Idol more viewers - 38.1 million fans tuned in for that.
