Want to know why it’s less important for Apple to have the top overall market share for smartphone sales? It’s all about the value that iOS devices can produce for the company and new data from Opera’s global advertising network shows that iOS is very valuable indeed. The Next Web reports that Opera’s latest figures show that iOS devices generate almost half of all mobile ad revenue across its network while Android devices account for just 28% of all mobile ad revenues. Things are even grimmer for other mobile platforms, however: BlackBerry generates 5.4% of revenues, Symbian generates 1.6% of revenues and Windows Phone generates a mere 0.3% of revenues. The iPad is obviously a big part of Apple’s dominance in the mobile ad world, but even when you take it out of the equation, Apple’s iPhone still generates 36.5% of all mobile ad revenues, which is more than Android’s total market share for both phones and tablets.
