There are several series that can be rented for $1.99 per episode. You can buy the episode, hovwever renting it gives teachers the opportunity to try the video with their class before they invest a greater amount of money. My classes really enjoyed the series produced by Teacher's Discovery under the label Moo!. They have several cultural topics including food and holidays. Each of the videos are about thirty minutes long. They are interesting to students because the camera follows a native host as they introduce the culture to an American teenager.

Another series that is available to rent are the Globe Trekker episodes produced by PBS. Each episode highlights a different country. The host visits iconic places and explores local rituals.
There is a series of educational videos available for free with an Amazon Prime membership. These are produced by New Dimension. They are a little bit drier and more like a documentary than the ones mentioned above. But they are well-organized and contain a lot of valuable information about culture including geography and history.
