Time to troll!
The reason it's called YouTUBE is because the word tube is in reference to the TV (hence the phrase "down time in front of the tube"
Therefore, if it no longer supplied videos and instead gave audio, it would be YouStation.
Also, learn some grammer :P
It was meant to sound like 'Eustachian Tube', the tube inside the middle ear, therefore relating to sound and hearing, but clearly no-one got this.
Oh well no cuz nobody knows earnatomy but that is definitely intelligent humor :P
