There were rumours doing the rounds that the results of the show
were rigged to boost the ratings by creating controversy. The
elimination of Pia Toscano, who had been regarded by Las Vegas
oddsmakers as this season's favourite, added more fuel to the fire.
But producer of the show Nigel Lythgoe rubbished it off by saying
that Toscano was no frontrunner.
“There are always conspiracy theories, but you know we are so
careful," New York Post quoted him as saying. He said that the vote
is tabulated by AT&T. “We get the results. It's done so
openly.. Let's take [Season 4,] the Carrie Underwood season. Carrie
Underwood won every single week. ... You show the vote, and the
show is over. There's no jeopardy if you're watching somebody win
every single week," he added.
