I don't reckon they make much of a profit anyway or any day, they own Youtube because of the reach, bragging rights , because of its potential, because of the worth .... ***porn.com - they struggle to make cash aswell and have tried to sell their website (no one wanted it though). Sometimes they just survive because of the hype and other uses (that aren't of a monetary value).
Um yes of course .... no ad's being displayed = no clicks or revenue. But I still think they'd loose money every day .... not just for being down .... so may be they saved money
