50 million. That's a pretty big milestone, and it's one that Sony has just hit with the PS4.
But it's also important for another reason: it means the PS4 has now outsold the SNES too.
Released back in 1990, the Super Nintendo Entertainment System has sold just over 49 million units. That's according to the consolidated figures Nintendo released in October, at any rate.
And that's a great figure. It means the SNES is the 13th best selling console of all time. It was in the top 12, until it got knocked off by the PS4.
It's a good indication of how this generation has gone. The PS4 launched in late November 2013, and had sold more than 40 million consoles by May this year. We don't know precisely how well the Xbox One is doing - because Microsoft stopped releasing those figures - but three years in, the PS4 is one good year away from surpassing the 3DS.
