I love YOUTUBE!  YouTube is an American video-sharing website
What do you mostly watch on youtube?
I like Buzzfeed mainly, The service was created by three former PayPal employees
Is Buzzfeed on you tube? the Paypal employees created Buzzfeed or you tube?
Chad Hurley, Steve Chen, and Jawed Karim created youtube, they are all former youtube employees 
You mean former Paypal employees, I guess. And when was you tube founded?
That was in 2005, in 2006  Google bought the site in November 2006 for US$1.65 billion
Did Goggle bought the site from the three founders?  If so, do you know if they founded something else with the money they got?
