The PlayStation 4 helped Sony regain its form after a slow start from the previous generation PlayStation 3, quickly dominating the console market.
And now, before the next generation consoles came out, the PS4 took second place, becoming the second best-selling console of all time with 102.8 million units sold. The PS4 surpassed the Nintendo Wii and PlayStation 1, currently behind only its brother, PlayStation 2.
Owning exclusive Nintendo titles, with a design that appeals to the mass market, the Wii sold 101.63 million units.
Meanwhile, PlayStation 1 sold 102.49 million units.
The PS4 tends to look like the Wii, selling after the promotion campaign, along with a series of exclusive titles by Sony studios. Games like Infamous Second Son and The Last of Us Remastered helped the machine generate traction, but it wasn't until 2016 that sales exploded.
After Bloodborne (2015), Sony released a series of games that are highly rated by experts every year, pushing sales more than Xbox One. Games like Horizon Zero Dawn, God of War, and Spider-Man quickly reaped success.
With The Last of Us 2 delayed until mid-2020, there's a good chance we won't see a major breakthrough for the PS4, as the time for the PS5 launch is near. But Sony is in a good position to prepare for its next generation, as it has sold more than double its main rival Microsoft – Xbox One is estimated to sell 41 million units.
The only popular console that sells more is the PS2, at more than 155 million. It is very difficult for any console to achieve that number.
The Nintendo DS is nearly achieved, selling 154.02 million, but it is only a mobile device, so it is not compared with the mainstream consoles. Similarly, Game Boy and Game Boy Color sell a total of 118.69 million units, making Nintendo second and third on the list if you include these mobile devices.
