Today is the 25th anniversary of the original PlayStation's launch, and Sony marked the milestone by announcing that the Guinness World Records had certified PlayStation as the "best-selling home video game console brand ever."
Between the four main PlayStation iterations, Sony has sold more than 450 million systems. Three of the four systems surpassed 100 million units in sales, with only the PlayStation 3 falling short while still managing to move 87.4 million units. Adding in the sales of the PSP (76.4 million units) and PS Vita (Sony has not disclosed a sales total), Sony has sold over 526 million gaming systems in its quarter century as a platform holder.
Sony's nearest competition for the best-selling home console brand would be Nintendo, but the Switch-maker's investor relations page puts its $#@!ulative home hardware installed base at about 323 million over 36 years (if one counts the Switch as a home system). However, adding in sales of portable systems including Nintendo mainstays like the DS and Game Boy puts the company's $#@!ulative sell-through at a little more than 752 million units.
