YouTube is the largest video sharing community online. There are literally millions of videos on every imaginable topic. It was created in Feb'05 by Steve Chen, Chad Hurley and Zawed Karim. Registration is completely free and users can upload and watch all the videos they want. YouTube accepts almost all video formats, offers 16:9 widescreen ratio high quality video playback and unlimited access to streaming. The only unsatisfactory thing is that the videos are limited to 15 minutes, very few long videos are available in the site.
