Each will receive $25,000 and be honored during a televised All-Star Tribute airing on Thanksgiving night, culminating in the crowning of Hero of the Year. The top hero will be selected by the public in an online poll, continuing through November 19 at the website, CNN.com/Heroes. The person receiving the most votes will win an additional $100,000.
