etymology of AMAZON.com - Amazing... isnt it!!!

Amazon.com – founder Jeff Bezos renamed the company Amazon (from the earlier name of Cadabra.com) after the world's most voluminous river, the Amazon. He saw the potential for a larger volume of sales in an online (as opposed to a bricks and mortar) bookstore. (Alternative: Amazon was chosen to cash in on the popularity of Yahoo, which listed entries alphabetically.)
