WP8 advertising

I was on youtube and looking at two videos compering the nokia lumia 920 and the iphone5 and before I got to the video I was interupted by an advert, then I heard the lumia920 tune and the advert and I thought how great, they have picked the perfect videos to advertise on. They were serious when they said they were going to get more aggresive in the advertising side of things.
