C Jeff Bezos will be stepping down as CEO of Amazon and will take on a new role as executive chairman. Facebook will be the only tech company in the "big five" that still has its founder as its CEO. This type of transition is common because it keeps the company's key visionary involved in big decisions. Amazon CEO Jeff Bezos announced on Tuesday that he will be stepping down as the CEO of the online retail empire he founded in 1994 and evolved into one of the world's most valuable technology companies. Andy Jassy, a long time lieutenant of Bezos and CEO of the company's booming cloud business, will replace him in the third quarter of 2021. But that doesn't mean Bezos is done with Amazon; he'll be stepping into a new role as executive chairman that will involve weighing in on big-picture decisions like product strategy and new projects.
