Last month, Apple CEO Tim Cook talked about something that had never been mentioned before in a podcast - Apple already has a very detailed successor plan. Cook stated that he hopes the next CEO will come from within the company. Since its establishment in 1977, Apple has served seven CEOs, and under the leadership of Steve Jobs' revolutionary ideas, Apple has become a highly competitive consumer electronics company; Cook, on the other hand, brought Apple to an unattainable peak: its market value rose continuously above $1 trillion, $2 trillion, and $3 trillion, becoming the world's most valuable company.
