General Motors received more reaction to its effort to eliminate the name “Chevy” than it has to any Chevy since about 1966. So the company backed down, rescinded the memo and invited its customers to continue to love Chevies and hopefully to resume buying them in large numbers too. Either that or some member of the corporate brain trust went outside their headquarters building, looked near the top and saw that the big blue letters don’t say “General Motors;” they say “GM.”
