"What is the website Youtu be?
Youtu.be is just a shortened URL that is also owned by Youtube and visiting either link still gets you to the same Youtube main page. Shortening web addresses is a good way of making it easier for people to remember it. ... Youtube.com uses the very popular .com Top Level Domain or TLD."
