This IDC study provides a five-year forecast for the mobile applications market.
"Accelerated growth in non-advertising app revenue is the headline for our latest forecast," said John Jackson, IDC's research vice president for Mobile and Connected Platforms. He continued, "2016's $45.4 billion total marked a 38% increase from the previous year, reflecting growth in the installed base of smart mobile devices to almost 3.9 billion while developers continue to perfect commercial formulas. Healthy top-line revenue growth was observed across all ecosystems including Google Play, Apple's App Store, and the extraordinarily vibrant Chinese market, which is dominated by independent channels. Consequently, we have raised our overall revenue forecast to $75 billion in 2021."
