Total apps in App Store cost for 5billion $ which include both for iPhone & iPad. Apple  revealed that iTunes itself dragged in some $1.9 billion in revenue in just the second quarter of 2012. The store sells apps for iOS, as well as music, movies, podcasts and e-books, all of which contributed to the giant take. Apple receives a 30 percent cut of revenue generated by content sold through iTunes, which means that app developers and content makers shared some $1.33 billion in revenue from the digital portal. The leftover $570 million, Apple said, went to iTunes operational costs. Apple also said developers have made more than $4 billion from the App Store since it was launched in 2008. The iTunes economy defined as gross revenues transacted through it is now about $12 billion/yr. Over the last five years content owners (media and app) received a total of $24 billion while Apple spent about $10 billion to create those sales Seen as a retail business, iTunes costs about $3.5 billion/yr to operate.
