April 21 : Apple's appointment of longtime hardware chief John Ternus as CEO signals a renewed emphasis on its core strength in devices and focus on fusing AI capabilities into existing products to sustain growth, analysts said. Ternus, a 25-year veteran who has overseen development of key products including multiple generations of iPhone, will take the helm in September, succeeding Tim Cook after more than a decade of strong growth that saw Apple's market value swell to around $4 trillion.
