South Korea now has 10 million registered Smartphone users, according to a Korean Communications Commission report. In late 2009, there were only 800,000 registered users. However, in 15 months, the number has skyrocketed to 10 million users.

The introduction of the iPhone in November 2011 in Korea has triggered the growth of Smartphone distribution. The Korean Communications Commission estimates the number of Smartphone users to reach 20 million by the end of 2011.
