Apple just announced its fiscal second quarter 2013 earnings and, on the earnings call, revealed some information on its iTunes App Store. Apple said it now offers more than 850,000 iOS applications and that 350,000 of those applications are specifically designed for the iPad. The company also recognized $2.4 billion in revenue from iTunes, up 28 percent from the same quarter last year.

The growth is not necessarily a surprise considering Apple's iTunes range. Apple offers 35 million songs in 119 countries, 50,000 movies in 109 countries and 1.7 million iBooks. The app store is also available in 155 countries, which Apple says covers more than 90 percent of the world's population.
