Alphabet is an American holding company founded in 2015 to house Google and all of its web-based properties, as well as the increasingly diverse real-world ventures the Internet behemoth was swelling to encompass, from driverless cars and life-extension research to high-speed Internet. Google cofounders Larry Page and Sergey Brin created Alphabet as part of a bold restructuring through which they hope to nurture Google's multifarious ventures into significant businesses, rather than hobbies that drag on Google's earnings. Alphabet, like Google, is headquartered in Mountain View, California and helmed by Page as CEO and executive chairman (and former Google CEO) Eric Schmidt. Alphabet is no small gamble: Not all of its futuristic ideas will work, and visionary leaders may not be in large enough supply. But Page and Brin's willingness to reinvent themselves according to their growing ambitions almost 20 years into Google's existence is a model worth studying for people looking to create big change in the world.
