According to Citibank, the App Store will continue to be a major money maker for Apple, and they’re estimating it will see $2 billion in sales in 2011. According to estimates by Gartner, the global app market brought in $4 billion last year, and will skyrocket to $27 billion in 2013 — that’s not chump change.

They also claim that smartphone growth, which drove these insane numbers, was up by 53% in 2010, will grow 29% in 2011, and will then stabilize into an annual growth of mid-20%.

So just how big is the $2 billion they’re pegging on iOS app store being worth? That’s how big they think the entire online video advertising market will be in the same period.
