YouTubed, YouTubing

I wonder how long it is before the phrase YouTube becomes a verb/noun just like google did. Imagine this:nA: Hey, have you seen Jay Chou’s latest clip yet?nB: NopenA: I did some YouTubings last nite and found it, you should try YouTube it yourself.
They do sound fu
y, but given the popularity of YouTube it might as well become a reality.
Why do they called YouTube anyway? Is the Tube referring to TV tube, so YouTube is like your own TV station thing?
Someday even YouTube url might be put on one’s resume or business card. nA: Hi, my name is Felix, this is my business card, as you can see there, there’s my YouTube url where you can see some clips of my [ acting | singing | playing musical intrument ] performance.
