A woman whose group has rescued more than 12,000 women and girls from sex slavery has been named the 2010 CNN Hero of the Year. Anuradha Koirala was chosen by the public in an online poll that ran for eight weeks on CNN's website. CNN's Anderson Cooper revealed the result at the conclusion of this year's "CNN Heroes: An All-Star Tribute," which airs Thanksgiving night at 8 ET/5 PT on CNN.
