'American Idol' premiere ratings drop from last year

"American Idol" pulled an "X Factor" on Wednesday -- even after adding big name judges to the table, the ratings for the season premiere still dropped from last year. About 17.8 million people tuned in for a first look at Mariah Carey vs. Nicki Minaj, compared to last season's 22 million who watched last year's season premiere, featuring Jennifer Lopez and Steven Tyler.
