The TED Conference is expanding its iOS offerings with a new app that'll let users read short electronic books from the popular series of intellectual presentations. The new Ted Books app includes articles that are 20,000 words or less and can be digested in a single sitting. The platform that powers the app allows authors to create an interactive experience by embedding audio, video and social features into their books. New books are released every two weeks, and iOS owners can either buy books individually for $2.99 each or purchase a six-month subscription for $14.99. You can read more about TED Books on TED's website.
