Amazon also created "channels" to benefit certain causes. In 2004, Amazon allowed customers to donate $6 to $200 to the campaigns of 2004 US presidential candidates, providing links that raised $300,000 for the candidates. Amazon has periodically reactivated a Red Cross donation channel after crises such as Hurricane Sandy, Hurricane Katrina, and the 2004 earthquake and tsunami in the Indian Ocean. By January 2005, nearly 200,000 people had donated over $15.7 million in the US.
