YouTube is a video site where users can upload their own videos. It was founded in 2005 and has become very popular across the world. There have been some controversies with copyright infringements. As of November 2nd, 2013, The YouTube Channel is the #1 Most Subscribed Channel on YouTube. On December 8th, 2013, The YouTube Channel was beat by Pewdiepie, but then got back to #1 one day later on December 9th, but lost it only hours late to Pewdiepie once again.
YouTube has over 2 million users, it is one of the top online sites and it has an Alexa ranking at number 3. The site has several features, such as subscribing to users whom you like, this is also known as subbing or subs. Favorites videos you can save on your channel page and come back and watch at a later time. YouTube is one of the best online sites that is free, the only catch is that you must join to comment which is free, and that copyrighted material may be removed.
The displayed resolution of YouTube is 640x480 (480p), so it cannot display HD videos. However, if a video uploaded is 640x480 or higher, a small link appears below the video saying "View In Higher Quality". If this link is clicked, the quality is slightly improved, and now HD has been added.
You must be 13 or older to register an account on YouTube
