Game-related content generated $15.39B in U.S. last year

Digital, physical, or used — gamers don’t care. If it’s games, they will spend money on it.

U.S. consumers spent $15.39 billion on game-related content in 2013, according to industry research firm The NPD Group. That’s up 1 percent over 2012. Digital made up nearly half of all that spending, and it was also the only sector showing major growth.
