Per the report, 52% of all advertising revenue on Opera Mediaworks’ mobile ad platform comes from Apple devices. Much of that revenue has come from the increased volume of ads served on iPads, which now account for 8.3% of impressions and 20.3% of revenue.

iPads also generate more revenue per impression than any other device, largely due to the performance of video ads on tablets. Video ads on tablets have a revenue to impression ratio of 1.84, compared to .86 for smartphones.

Both Apple and Android tablets have doubled their market share of impressions from last quarter, and have twice the revenue potential of smartphones.

Mahi de Silva, CEO, Opera Mediaworks, stated that he expects the trends in video and high-value publisher categories to continue to drive growth in the mobile industry. He also stated that industry-wide growth has paralleled his own company’s growth, as Opera Mediaworks now reaches 1.1 billion unique users.

Breaking new revenue down by verticals, games took the lead from social networking in terms of revenue, accounting for 23.7% of revenue, though social is still the king of impressions at 18.7%.

Globally, the U.S. rate of video usage is two times the average, while developing markets in Latin America and the Middle East are closing the gap as their consumers shift towards smartphones. Users in the Mideast spend the majority of their time on the mobile Web, in stark contrast to U.S. consumers, who spend about 90% of their time in apps.
