Although the greatest number of Asian subscribers was in 2008, that is not the answer, because Asians formed a smaller percentage of subscribers in that year than they did in 2006. In 2008, there were roughly 15 million Asian subscribers and roughly 72 million total subscribers. The percentage of Asians in 2008 was therefore $\left(\frac{15}{72}\right)$ × 100 = 20.8%. In contrast, in 2006, there were roughly 10 million Asian subscribers and 42 million total subscribers. $\left(\frac{10}{42}\right)$ × 100 = 23.8%.
