Apple CEO Tim Cook has credited the company's recent retail innovations, which include the online option of in-store pickup of purchases as well as a new self-checkout option that incorporates into the stores' EasyPay system with an eponymous iOS app, with helping Apple Stores see significant jumps in visitors and revenue across 2011. Average revenues per store grew 43 percent to $17.4 million, while visitors grew 45 percent to an average 22,000 per week.
