Mashable: Groupon has already been a lot of things, not all of them successfully. Now, it might become a food delivery company. Groupon has announced the acquisition of OrderUp, an online meal delivery startup. Groupon CEO Eric Lefkofsky said that the move gave the company a bigger part of the $70 billion food ordering and delivery sector. “Online food ordering and delivery represents an untapped opportunity for Groupon and serves as a natural extension of our local marketplace.”
