Do go see a slide-show of all ten, here -- from Iacocca (Chrysler) to Cuneo (Marvel) to Bethune (Continental Airlines):

. . . . No. 2 | Dick Clark. . . .

No. 10 (of 10) | Steve Jobs. . . .

It is not clear whether the list is in reverse order, but as much as I respect Mr. Clark, I'd never rank his efforts ahead of the feat Steve Jobs pulled off, over the last decade -- as he returned to Apple. Of course (as Mr. Iaccocca reminds us!), your mileage may vary.
