Sharing videos via email, file transfer or using old technology like DVDs can be impractical. Uploading your videos to a service like YouTube that almost anyone can access is easy and useful. You can set these videos to be unlisted or private if you aren't interested in the general publicseeing them. YouTube videos can be viewed on computers, set-top boxes, TVs, tablets, phones. Plus, they can be high definition, giving them a big advantage over DVDs.
