In 2008, a Memphis-area philanthropist invited Wikipedia co-founder Larry Sanger, Ph.D. to design and launch a new, educational video library that would be managed collectively by practicing teachers using a wiki philosophy. Dr. Sanger served as the initial Executive Director for the the project, along with Walt Henley as the Marketing Director. Kerry Matthews, WatchKnowLearn’s former Director of Education served as interim Director in 2014. In 2015, Walt Henley returned as Executive Director after working on his Ph.D. at the University of Memphis. Since its inception, the website has shown over 50 million free educational videos to a US national and global audience of over 1 billion classroom students.
