Over the last year, the total time spent playing video games increased 7% and purchases of digital content and subscriptions rose 8% according to a study from Nielsen. Over half of all households, 56%, owned at least one current-generation gaming console as of January 2012, an increase from 50% in 2011. Mobile, handheld and tablet gaming continues to grow as well, with 66% of households with kids between 6 and 12 years old owning a Nintendo DS or Sony PSP, while also owning an iOS device. More adults ages 25 through 34 play games on Android devices than on iOS devices, but iOS gaming is evenly distributed across the various age groups covered by the study. As for next-generation game consoles, four out of five gamers who own current-generation systems are interested in a future console.
