Did You Know? originally started out as a PowerPoint presentation for a faculty meeting in August 2006 at Arapahoe High School in Centennial, Colorado, United States. The presentation "went viral" on the Web in February 2007 and, as of June 2007, had been seen by at least 5 million online viewers. Today the old and new versions of the online presentation have been seen by at least 10 million people, not including the countless others who saw it at conferences, workshops, training institutes, and other venues.
