In 1997, Oprahâ€™s Angel Network launched as a campaign that encouraged viewers to collect spare change, but evolved into a network of giving that extended to 30 countries around the world. To date the organization has built 55 schools in 12 countries; donated over $1 million of supplies to 18,000 South African children; relocated more than 1,000 Gulf Coast families to their homes after Hurricane Katrina; and awarded grants and scholarships for various causes. Although the charity was shut down last year, Winfrey continues to operate two private philanthropy organizationsâ€”the Oprah Winfrey Foundation and the Oprah Winfrey Leadership Academy Foundation. According to the Chronicle of Philanthropy, which ranked Winfrey as No. 25 on their annual Philanthropy 50, she donated more than $41 million to charity last year.
