Thanks to Jim Collins and Good to Great, "quiet" CEOs are the rage these days. I don't subscribe to noisy-for-noisy's-sake, but I do believe the Buzz surrounding a Welch or Gates or Branson or Buffet can add billion$$$ to market cap. Burson-Marsteller would seem to side with me ...
"Surveys conducted by PR giant Burson-Marsteller suggest that 50% of a corporation's reputation is attributable to that of its CEO." —Fortune/11.15.04
(Hint I: 50% is a lot!)
(Hint II: This holds for a local, buzz-worthy restaurateur as much as for BigCo's CEO.)
