Academic Earth is an online repository for videotaped lectures presented by leading academics. Lectures are organized by lecturer, university, subject, and theme.Previously, such filmed lectures would be accessible only through a portal like I-Tunes University. The advantage of Academic Earth is that it doesn't require the user to download a program like I-Tunes--which is an issue for online instructors who don't wish to require students to install I-Tunes on their home computers as well as for instructors working in computer labs where I-Tunes is not installed.
