Digital agency Proximity Chicago is now known as Xi (pronounced “Chee”). The name “Xi” literally came from the heart of our o ... riginal Proximity name, and Xi continues to serve as the digital center of Energy BBDO. We’re still part of Proximity Worldwide (the world’s most award-winning digital, direct, and CRM network) and BBDO (the most awarded agency network for effectiveness and creativity).
