According to the NPD Group, a 2011 survey analysis estimated that 91 percent of children in the United States between 2 and 17 years of age play video games. Overall, children are approximated to contribute to 44 percent of new software sales. The types of gaming systems with the largest growth include computers, smart phones and tablets. Android and iOS games appear to be the most popular among children.
The NPD Group notes that in the second decade of the 21st century, traditional gaming systems such as Nintendo and PlayStation have had a difficult time keeping up with the growth of the gaming industry, particularly related to handheld devices such as smart phones and tablets. This is presumably due to the fact that children find handheld systems to be more convenient and easier to use.
According to the NPD Group, another factor that boosts Android and iOS sales is the fact that many large software companies are making games and apps available for download on handheld devices. These games and apps were previously only compatible with traditional gaming consoles, such as the Sony Playstation, Microsoft Xbox and Nintendo Wii.
Companies like Nintendo have had to lower the prices on their products in an effort to make up for decreasing sales and compete with companies such as Apple and Samsung.
