Google's app store revenues are growing much faster than those of Apple Inc.
App Annie, an analytics firm, showed Google's app store revenues were 38.5 percent of Apple's, a big gain from a year ago when it was worth just a tenth of Apple's, as its free Android mobile operating system helped it win nearly 70 percent of the global mobile market.
Fuelled by roaring growth of Android mobile devices, largely manufactured by Samsung Electronics and up-and-coming rivals, Google Play revenues jumped 90 percent in the first quarter from the fourth quarter, according to App Annie.
