It's been made official: PlayStation is the best-selling home video game console brand ever. Across all its major platforms (not counting portables), Sony has sold over 450 million units, comfortably dominating the home console space over its 25-year existence. The fact has now been acknowledged by Guinness World Records, with the establishment recognising the achievement with one of its signature certificates.

Now seems like as good a time as any to receive this record. Today, Sony is celebrating the 25th anniversary of PlayStation, so we'll bet Jim Ryan and all at the company will be chuffed to bits with this. Stick that certificate on the fridge, everyone; you've earned it.
