Research suggests that gaming is more popular than digital music and video among children aged between two and fourteen years.

According to findings from research group NPD, 85% of all electronic devices used by children in this age group were used for gaming. 60% of youngsters use them to listen to music, 22% download ringtones, while one third watch videos.

"Although the most dramatic increase in usage of these devices happens at about age nine, playing games appears to be an activity that first engages young kids with the digital world," said NPD analyst Anita Frazier.

"Our study finds that 82% of kids aged two to five play games on one or more of the devices surveyed."
