$150 million marketing campaign for Modern Warfare 2? Can you please redirect me to a link mentioning that?

jst google it

Yup not finding it.  Link please?  Only thing that came up was another VGChartz thread speculating that it may have cost around $150 million for the ad campaign.  No official numbers that I saw.
