Sony has today announced that 91.6 million PlayStation 4 units have been sold as of December 31st of, 2018. This is thanks to the 5.6 million units that were sold during the 2018 holiday season (November 19th-December 31st). This is a pretty impressive feat considering the PS4 only launched 5 years ago.
Spider-Man was also a massive seller for Sony, shifting more than 9 million copies worldwide (includes both physical and digital numbers). This doesn’t include the month of December either, meaning it likely tipped over the 10 million unit mark.
