Amazon CEO Jeff Bezos and his wife, MacKenzie, are divorcing, ending a 25-year marriage that played a role in the creation of an e-commerce company that made Bezos one of the world's wealthiest people. The decision to divorce comes after a trial separation, according to a statement posted Wednesday on Jeff Bezos' Twitter account. He and his wife both signed the announcement, which ended with a vow to remain "cherished friends."
