Revenue from app stores will grow 77.7 percent in 2011 to $3.8 billion. The Apple App Store is expected to be 75% of the market, according to IHS Screen Digest research.
The Apple App Store leads, with this year's revenue expected to be $2.91 billion, up 63.4 percent from $1.78 billion in 2010.
Total download revenue from games and other applications are projected to continue rising in the next few years, jumping to $5.6 billion in 2012, $6.9 billion in 2013, and $8.3 billion in 2014.
Google's Android Market will see the fastest growth in 2011. Android Market revenue will soar 295.4 percent this year to $425.36 million, on its way to becoming the second-largest application store.
The BlackBerry App World will finish third with expected revenue of $279.11 million.
In last place this year will be the Nokia Ovi Store, with $201.48 million in anticipated revenue and 1.1 billion downloads from Nokia's Symbian smartphone users.
The total number of downloaded applications in 2011 is expected to reach 18.1 billion by year-end, compared to 9.5 billion last year, 3.1 billion in 2009 and 419.2 million in 2008. By 2014, downloaded applications will top some 33 billion.
75%? I'm not sure that this number is possible. Especially after the latest Apple scandal. Mobile application development is varied and people can prefer Android or Blackberry (by the way the latter one is more secuire).
