The company that experienced perhaps the most radical change from original logo to current one is Apple. The company's first logo was designed by one of the original three co-founders, Ronald Wayne. Wayne isn't the household names that Steve "Woz" Wozniak and Steve Jobs are because he quickly traded in his 10-percent share of the company two weeks after it was founded for a measly $800.
But during his short time at the company he designed one extremely detailed logo: that of Sir Isaac Newton sitting under a tree which is about to drop an apple on him. If he had kept his share he would be a billionaire 35 times over.
Apple didn't keep Wayne's logo for even a full year. Jobs ordered a new, simpler logo. He soon got the iconic rainbow colored apple with a bite taken out of it.
Jean-Louis Gassée, the former head of Macintosh department, famously said that "one of the deep mysteries to me is our logo, the symbol of lust and knowledge, bitten into, all crossed with the colors of the rainbow in the wrong order. You couldn't dream of a more appropriate logo: lust, knowledge, hope, and anarchy."
Apple has only had three logos. Wayne's, the colorful apple, and in 1998 the company lost the colors and went to either a solid black or a simple white apple.
