YouTube is a website where you can upload your movies (up to 100Mb per movie) and share them with the whole world. YouTube even makes it possible for owners of websites/blogs to show YouTube videos on their own site. To test how/if this works I put this short movie of Borat (Sacha Baron Cohen) online.
By introducing services like this the amount of vodcasts will rapidly grow on the web. Fifteen seconds of fame for everyone.
