Apparently less people are watching “American Idol.” The season finale on Wednesday night hit a new low for the show with an estimated 21 million views tuning in to see Phillip Phillips crowned as the 11th “Idol,” according to preliminary Nielson research. Wednesday’s finale was watched less than any other “Idol” finale. Is “American Idol” in trouble?

The number was down by nearly one-third from the 29.3 million viewers who saw country singer Scotty McCreery’s victory a year ago, an audience total that had rebounded by 20 percent from the finale in 2010.
