The PlayStation 4 (officially abbreviated as PS4) is an eighth-generation home video game console developed by Sony Interactive Entertainment. Announced as the successor to the PlayStation 3 in February 2013, it was launched on November 15 in North America, November 29 in Europe, South America and Australia, and on February 22, 2014 in Japan. It's the 4th best-selling console of all time. It competes with Microsoft's Xbox One and Nintendo's Wii U and Switch
The PlayStation 4 was released to critical acclaim, with critics praising Sony for acknowledging its consumers' needs, embracing independent game development, and for not imposing the restrictive digital rights management schemes like those originally announced by Microsoft for the Xbox One. Critics and third-party studios also praised the capabilities of the PlayStation 4 in comparison to its competitors; developers described the performance difference between the console and Xbox One as "significant" and "obvious". Heightened demand also helped Sony top global console sales. By the end of September 2019, over 102 million PlayStation 4 consoles had been shipped worldwide, surpassing lifetime sales of the PlayStation 3.
On September 7, 2016, Sony unveiled the PlayStation 4 Slim, a smaller version of the console; and a high-end version called the PlayStation 4 Pro, which features an upgraded GPU and a higher CPU clock rate to support enhanced performance and 4K resolution in supported games
