Apple recently delivered its 1 billionth application download from the App Store, which currently features more than 25,000 apps built by thousands of developers. I has taken only nine months from when the App Store launched on iTunes to hit 1 billion paid and unpaid downloads.

Last summer, Apple sold one million 3G iPhones worldwide across 21 countries in the first 3 days on sale. During that same time, iPhone users made 10 million app downloads from the then newly launched iTunes App Store.

The App Store hit 500 million downloads by January 16, and it took Apple six months to reach the first 500 million downloads. It would take Apple only three months to get another 500 million downloads.
