Sixty-five percent of children under eight years old watch television daily. On average, they spend about an hour and a half (100 minutes to be exact) watching TV every day. As a group, children under eight spend an average of 25 minutes per day playing video games. 66% of all children under the age of two have watched television. Television watching typically begins at 9 months of age.
While industry figures find that the average age of a person who plays video games is 37, new data from The NPD Group suggest that there's little to worry about when it comes to a constant influx of new gamers. That's because 91% of U.S. kids ages 2-17 play video games, up 9% from two years ago. The percentage of youngsters who take up gaming (12.68%) is actually growing faster than the growth rate (1.54%), the tracking firm finds. And kids represent a huge chunk of the spending on physical game software -- 44% in 2011.
