Shared online videos have become quite popular. These streamed videos are so pervasive that 69% of Internet users and 52% of adults in the United States have watched or downloaded videos online (Purcell, 2010). It was predicted that videos would represent 50% of total data transfers on the Internet by 2012 (Madden, 2007). These statistics leave little doubt as to the rising importance of shared online videos for educational purposes.
