The PlayStation 4 (PS4), developed by Sony Interactive Entertainment, launched on November 15, 2013, as the successor to the PS3, competing in the eighth generation against the Xbox One and Wii U. Moving away from the complex Cell architecture, it featured a powerful AMD x86-64 APU (peaking at 1.84 teraflops) and emphasized social features like Remote Play and Share Play, alongside a redesigned controller with a touchpad. The console was critically acclaimed for its consumer-friendly approach, notably avoiding the restrictive digital rights management (DRM) that initially plagued Microsoft's Xbox One, which helped it dominate global sales. In September 2016, Sony released a smaller "Slim" revision and a high-end PlayStation 4 Pro with an upgraded GPU for enhanced 4K performance. By October 2019, it became the second best-selling PlayStation console ever, behind the PS2, before its successor, the PlayStation 5, arrived in November 2020.
