Steve Jobs and Steve Wozniak founded Apple Computer Inc. in 1976 to sell the Apple I personal computer kit. The company's name and first logo, featuring Isaac Newton under an apple tree, were designed by co-founders. In 1977, Rob Janoff designed the modern rainbow-colored Apple logo. Steve Jobs later simplified it to a solid color. Over time, Apple expanded its product line from personal computers to include the iPod, iPhone, iPad, and software like Mac OS X, iTunes, and iLife apps. Apple's vision is for people to use technology that enhances creativity and independent thinking.
