The Discovery Network's "Monsters and Mysteries" is doing an episode on Slenderman next season. The premise of the episode is based on my book, "Slenderman: From Fiction to Fact". It focuses on the manifestation of the Slenderman entity, with personal stories from eye-witnesses.
Stay tuned for the air date!
UPDATE: Due to a third party (not creator Eric Knudsen/Victor Surge) they will be changing the name from Slenderman, since someone (possibly a motion picture studio)has filed a copyright on the name "Slenderman".
