Dear teacher,
what does “Youtube” mean?

Television is sometimes referred to as "the tube".

Cambridge Dictionaries Online - Cambridge University Press

The "you" part of the name puts emphasis on the fact that anyone (i.e. you!) can broadcast homemade videos to an audience: much like a real television company, but over the internet.

Youtube = yourTV.
