In an earnings report released Tuesday, Sony revealed it sold 3.2 million of the game consoles in the quarter that ended June 30, pushing it to the 100 million unit sales mark.
Sony debuted the PS4 in November 2013 and by December 2017 had sold over 70.6 million units worldwide.
In 2017, Sony console sales underwent a resurgence as newer, better PlayStation games, such as Dragon Quest XI, Injustice 2 and Madden, hit the market.
According to analyst Dan Ives, the PS4 has sold well above competitors, calling the 100 million "an impressive number."
Sony hasn't released a new generation console since the PS4 although it did debut an iteration, the PS4 Pro, in September 2016.
