The data, compiled in the month of May, charts ad impressions on the InMobi ad network, which says that it serves 35.7 billion monthly mobile advertising impressions worldwide, with 3.8 billion of those in Europe.
InMobi notes that a lot of the growth for Apple, which now has a 19.5 percent share of the market (a rise of 6.3 percent over the past three months), was led by ad impressions on the iPad. The tablet had 80 million impressions during the month in the region, making it the sixth most-popular mobile device in Europe.
Android’s share has gone down by 6.1 percent in the past three months, although it still remains the biggest mobile platform in terms of ad requests—that is, taking all Android handset makers’ impressions collectively. And iPhone still remains the single most popular device."
