His work has been widely cited in the New York Times, Fortune Magazine, the Wall Street Journal, the Financial Times, CIO Magazine, the Boston Globe, and the Christian Science Monitor. He has also been interviewed on NPR's "Morning Edition" and "Talk of the Nation."

A former researcher at both Harvard Business School and MIT's Sloan School, he was also co-author (with J.F. Rockart) of Executive Support Systems: The Emergence of Top Management Computer Use. Dr. DeLong has lectured in the U.S., Europe, Australia, and South America, and is a widely-published writer whose work has appeared in journals and magazines such as Harvard Business Review, The New York Times, The Boston Globe, Newsweek International, Organizational Dynamics, Computerworld, and Inc.
