Should large companies prioritize promoting long-term internal employees to the CEO position?

John Ternus has officially taken over as the CEO of Apple, ending a 15-year tenure by predecessor Tim Cook. Ternus, who is 51 years old, assumes leadership of the company as it maintains a market capitalization of $4.6 trillion.

Why it matters

This transition marks a leadership shift for one of the world's most valuable technology companies after a decade and a half of relative stability. Ternus takes control of an operation that has defined global consumer electronics manufacturing and supply chain management.

Ternus has been at Apple for 25 years, joining as an engineer in 2001 at the age of 26. He brings experience overseeing the company's hardware architecture, having served as vice president of hardware engineering starting in 2013.
