The ambitious Year Zero alternate reality game (ARG), a work of cross-media art involving websites, emails, phone calls, album packaging, tour t-shirts, thumb drives, music videos, murals, and live concert events with the new music of Nine Inch Nails at its core. Playing out over 10 weeks, the Year Zero ARG engaged over 2.5M participants. It started with a message hidden in the back of a concert t-shirt that lead to online websites - ultimately over 29 websites discovered over several months, 7.5M page views, 7M forum postings, 2M phone calls and thousands of original art submissions.
