Tim Cook steps down as Apple CEO

After a transformative 15-year tenure that saw Apple's market valuation reach $4 trillion, Tim Cook is preparing to hand over the reins of the technology giant.

John Ternus, a 25-year veteran of the company known for his engineering precision, has been named the incoming CEO. This leadership transition comes at a critical juncture as Apple faces intense pressure to catch up in the global artificial intelligence race.

Cook will remain involved as executive chairman, focusing on policy engagement and supporting the transition as the company enters a post-iPhone era.
