"Safe and steady" was the theme of May's NPD figures, with no console either enjoying a majestic surge or suffering a crushing collapse -- the DS simply registered a decent if unspectacular 9% rise in hardware sales. As it turns out, that bump was timely, because it meant the console reached 20 million units sold in North America, a landmark that has now been passed in all major regions.

Of course, we could snicker at how the PSP only clinched 29% of the handheld market, and so we will.
  • Wii: 714.2K 39.1K (5.5%)
  • DS: 414.8K 37.8K (9.1%)
  • PSP: 192.7K 10.4K (5.4%)
  • Xbox 360: 188K 1.4K (0.8%)
  • PS3: 187.1K 21.6K (11.5%)
  • PS2: 124.4K 8.3K (6.7%)
Software sales are waiting past the break.
