YouTube is one of the most popular video streaming websites on the Internet today. Created back in early 2005, and acquired by Google in 2006, YouTube allows users to upload short video clips – everything from music videos to movie trailers to TV show episodes and homemade videos.
Members can subscribe to their favorite video feeds using an RSS feed feature and receive updates when new videos are posted. Many of the videos available on YouTube can be embedded into online social network profiles and emails with a special HTML code accompanying the video.
