People have downloaded over 40 billion apps from Apple’s iOS App Store (not counting re-downloaded apps), the technology giant announced today.

The App Store, which launched about four years ago, currently features more than 775,000 apps for various device platforms (iPhone, iPad, iPod Touch) across 23 categories. And while the 40 billion download milestone is impressive, what’s more impressive is that about 20 billion of those downloads happened in 2012, according to Apple. Also, about 2 billion downloads occurred in December alone, which makes sense because of the holiday shopping season rush.

The news comes a week after independent research firms reported that both Christmas Day and Christmas week saw record-breaking numbers of iOS device activations. So, it’s no wonder that December proved to be a big month for Apple’s App Store.

Apple also revealed that it has over 500 million active iTunes accounts, meaning that the company has roughly 500 million credit cards on file that are eligible to make purchases on the App Store. Also, developers have made $7 billion in revenue (not counting Apple’s 30 percent cut) since the App Store launched in 2008.
