there are 400 million Internet-connected devices in American homes these days, 39 million of which are video game consoles.
The majority of connected devices (about 184 million) are still plain ol' desktop and laptop computers, and smartphones are in second place with about 133 million devices. Video game consoles come in third, right above tablets (31.8 million) and connected HDTVs (16 million), which means there's a significant number of game-oriented devices out there plugged into the Internet.
The NPD says it expects these devices to start connecting to each other more in 2013, with smartphones and tablets doing more sharing to larger television screens. Video game consoles serve plenty of functions outside of pure gaming already, including video streaming, networking, and Internet browsing. NPD's report says that if smartphones and tablets can provide those services in a combination that appeals to customers, those categories will continue to grow this year, possibly even leaving dedicated game consoles behind.
