Terrifying statistic incoming. According to research performed by the NPD Group, 14% of American homes have an online game subscription. Not 14% of homes connected to the internet. 14% of homes.
That figure covers any and all games requiring a subscription, so don't go laying all the blame at World of Warcraft's feet. Spare a little for EVE, Age of Conan and LOTRO as well.
"Despite concerns that the recession would cause consumers to reduce spending on entertainment subscription services, most forms of subscription entertainment are doing just fine," NPD's Russ Crupnick said in a press release. "Consumers are clearly looking to the value offered by entertainment subscriptions and like what they get for their money."
