YouTube is monetising one billion videos a week

" YouTube is now monetizing over a billion video views a week. Last week, YouTube announced that it was serving over 1 billion video views a day, so if you do the math there, it means that YouTube is monetizing one every seven video views.
The company also noted that 90% of the top 50 advertisers according to AdAge have now run ads on YouTube. And of its homepage ad inventory, 90% of it sold out for the quarter in the U.S., with lower, but still impressive sale rates for the rest of the world. Google also noted that YouTube was just starting to unleash its pre-roll inventory and let its salesforce have a go at selling that to advertisers, which should bring in more money."
