Amazon founder Jeff Bezos on Monday will hand over his chief executive title to Andy Jassy, ending a more than two-decade run leading the company through its evolution from online bookseller to $1.75 trillion global retail, logistics and internet behemoth. The company announced in February that Bezos would transition from CEO to executive chair, saying he wanted to spend more time on his other ventures, including the Washington Post, space company Blue Origin and philanthropy.
