On its recent earnings, McDonald's stressed the importance of connecting with its customers digitally.
"We're also accelerating our digital efforts, as we've talked about before, leveraging learning from markets like France and Australia, who are now executing some elements of our e-commerce digital strategies," said CEO Don Thompson on the company's last earnings call. "We're also testing various additional elements of our strategy in other markets, like the U.S, Sweden and the U.K., as we refine and execute our global digital vision."
Thompson already has said the company plans to place greater emphasis on digital in its media mix.
To that end, McDonald's opened a San Francisco outpost in June. Far from its Midwest roots of Oak Brook, Illinois, the company wants "to create a presence in the heart of the tech community" and enable it "to attract world-class talent from the digital industry," Hary said.
