FTC Probe Cited in VC's Departure from Amazon Board

Last month, John Doerr, one of America’s most celebrated venture capitalists, announced that he would step down from the board of Amazon.com, a company that he helped to finance and build. People with direct knowledge of the matter, who would not speak for attribution because they were not authorized to discuss it, now say Mr. Doerr’s decision was prompted by a Federal Trade Commission inquiry into the relationship between Amazon and Google, where Mr. Doerr is also a director.
