TeacherTube (www.teachertube.com) is similar to YouTube, except that it contains only educational content. In addition to ESL, some other subjects include: high, middle, and elementary school subjects, world languages, fine arts, writing, reading, math, etc. Here are some interesting ESL videos I found on TeacherTube.
The nice thing about this site is that you can download the videos. You can use them in class without an Internet connection.
