A sad day for the dozens of GM fans around the world: They must bid farewell to the iconic GM logo. Created in the early 1960s, the logo once represented global brand strength. Now, it is just another brand anchor around the necks of Chevrolet and Cadillac, among others. GM announced it will gradually phase the logo out starting in 2010.
