I’m not certain whence the idea about Jeff Bezos naming Amazon.com because he views the internet as “a great river of commerce”. A former high-up amazon staffer, q.v. http://www.amazon.com/exec/obidos/subst/misc/dr.html/002-4620352-8272052, informed me that the answer was much more simple. Bezos wanted a good name that would come at the beginning of an alphabetized list. Similar reasons for company names abound. My favorite example is a family in Long Island where the father owned a trucking company and then his sons and brother started their own firms. They went through something like twenty names between them, with the winner finally sticking a meaningless “AAA” at the beginning of his.
