How it spread

Trace the origin

Warner Bros. and 42 Entertainment began the ARG in May 2007. Fans unlocked images, solved street hunts and campaigned for Harvey Dent. The agency claims over 11 million participants. The film’s record opening was a wider commercial outcome, not an attributable ARG return.

Documented milestone; not a measured attention peak. Dates use the stated precision; chart positions are date anchors.
