Nintendo's sales statistics this gen have been impressive across the board (except for Wii Music, which the company admits underwhelmed at retail), but this one is a doozy.

The company has released lifetime sales data for the mighty DS, covering all three iterations, and market penetration in the US and Europe hovers just below the 10% mark. In Japan, the DS has carved out a nifty 20.5%. That's 26.1 million DS' sold to a population of 127 million. That's one out of five people for a specific video game console.

Since this includes lifetime sales, it's important to note that this doesn't mean one out of every five people in Japan own a DS, as it doesn't take into account individual users who've made multiple purchases or upgrades. But still, it's an impressive figure nonetheless.

It really does print money.
