Research reports forecasting future market sizes should always be taken with a grain of salt, but it occasionally helps to see the estimates of research organizations in order to gain some perspective on the current and upcoming trends for those markets.

An upswing in the market share of "smart" devices, along with an increase in application focus from OEMs, OS developers and mobile network operators will drive yearly app revenues from US$1.94 billion (2009) to US$15.65 billion in only four years, according to our most recent research findings.

The application market's growth is driven by the widespread push of advanced handset capabilities by the mobile industry and the increasingly-connected global consumer base. This trend will continue, seeing global smartphone users numbering 970 million by the end of 2013.
