Tim Cook steps down as Apple CEO

In a landmark transition for the world's most valuable technology company, Tim Cook has announced he will step down as CEO of Apple.

Cook, who inherited the role from Steve Jobs in 2011, oversaw an era of unprecedented financial prosperity and the launch of iconic products like the Apple Watch and AirPods.

He will remain involved with the Cupertino giant as executive chairman of the board.

John Ternus, a low-profile but highly influential hardware executive, will take the helm as the company navigates a shifting landscape dominated by artificial intelligence.
