Apple has announced some executive changes, promoting Jeff Williams to the chief operating officer role vacated by CEO Tim Cook, and making Phil Schiller head of the App Store in addition to his current role as senior vice president of worldwide marketing. The company also announced two new executive additions, with Johny Srouji becoming senior vice president for hardware technologies, and Tor Myhren joining the company from advertising firm Grey to become vice president of marketing communications.

"We are fortunate to have incredible depth and breadth of talent across Apple’s executive team. As we come to the end of the year, we’re recognizing the contributions already being made by two key executives," said Cook in a press statement. "Jeff is hands-down the best operations executive I’ve ever worked with, and Johny’s team delivers world-class silicon designs which enable new innovations in our products year after year." Cook added that Schiller will be taking on "new responsibilities for advancing our ecosystem, led by the App Store," and welcomed Myhren's "creative talents."
