Apple's quarterly earnings may be stagnant, but at least one division within the company is showing extraordinary growth. As noted by Asymco analyst Horace Dediu, Apple's iTunes/Software/Services division grew by 34 percent year-over-year after taking into account the 70% Apple pays to developers for App Store purchases. Dediu estimates that Apple's gross revenues from the iTunes/Software/Services group are almost $7 billion per quarter, with a total of $23.5 billion for 2013. This includes growth categories such as third-party content (+46.6 percent), Services (+37 percent) and apps, which grew 105 percent year-over-year. This division is remarkable when compared to rival Google and other Fortune 500 companies.
