In May, 38 percent of the unique iPad devices in AdMob's network came from outside of the US. The top five iPad countries in AdMob's network, based on the number of unique devices, were the United States (58%), Japan (5%), United Kingdom (4%), China (4%), and Canada (3%). There was a dramatic increase in the number of unique iPad devices used in Japan, the UK, and Canada last weekend. But there was a strong iPad usage in China since the device first launched. This data is based on the approximately 850,000 unique iPad devices in May in the AdMob network.
