Which company developed the PlayStation game-console brand and is part of Sony Group?

Sony Interactive Entertainment developed the PlayStation game-console brand and is part of Sony Group.

Sony Interactive Entertainment, previously known as Sony Computer Entertainment, manages PlayStation hardware, software, services, and related business operations. The original PlayStation launched in Japan in 1994 and later became a major force in the global video-game industry.

PlayStation consoles, games, online services, and accessories contribute to Sony Group’s broader technology and entertainment businesses. Sony Group is also active in music, films, television, electronics, financial services, and image sensors, so its market capitalization represents more than the PlayStation operation alone.

A common mix-up is answering “Sony,” which is the parent group, when the question asks for the specific gaming subsidiary. Sony Interactive Entertainment is the canonical corporate name for the PlayStation business, while PlayStation is the consumer brand used for its products and services.
