In a recent report from the United Nations Development Program (UNDP), of 2,597 Cambodian people between the ages of 15-24, 98% reported that they used their mobile phones mostly for making and receiving calls, 43% for listening to the radio and 32% for sending and receiving messages, followed relatively closely by playing and downloading games (27%) and taking photos (22%). Of those youth who used SMS, the majority used English language messages (81%). In the Asian-Pacific countries, the number of mobile social media users was set to reach one billion by the fourth quarter of 2015; and in Cambodia increasing 108% from the previous year. The number of people in the region accessing social media from mobile devices jumped an impressive 32% in the past year, to reach 900 million. In Cambodia, about 80% of the traffic is driven by Facebook and YouTube. The proliferation of smartphones has catapulted Facebook to Cambodia's second-most important source of news this year, surpassing radio and edging ever closer to overtaking television.
