The non-profit educational organization TED (Technology, Entertainment and Design) believes passionately that ideas have the power to change attitudes, lives, and ultimately, the world. Their motto is "ideas worth sharing." TED-Ed animations are short, award-winning educational videos narrated (in clear English) with lightness and humor. They are brought to life by professional animators who make learning fun. They're "lessons worth sharing."
