This week, I received a link from my fellow Personal Brand Strategists, with a video clip about the rise and fall of Kodak. Kodak, which one employed over 145,000 people, now employs less than 20,000. The firm’s traditional products and corporate brand were wiped out by the digital revolution. Kodak’s CMO, Jeffrey Hayzlett, has a tough job and he talks about it in this very entertaining video about marketing, branding and life in the fast lane. The LESSON: know your differentiation and competition, innovate and stay on top of your game.
