How video game history has changed

Since 1994, PlayStation's five consoles have changed video game history.

Grey or bust

The PlayStation, launched in Japan on 3 December 1994, was grey - inspired by the "workstation" computers of the era.

"The heads of Sony's US division would have preferred black, which they felt was more elegant, but the Japanese side categorically refused," Maeda said.

They relented, however. Apart from colourful limited edition versions, the PlayStation 2, 3 and 4 were black. The PlayStation 5, released in 2020, is white.

Joystick juggling

When Sony built the first PlayStation, it was inexperienced in making consoles, so "the creation of the controller was one of the biggest challenges", Maeda said.

"It's said they made more than 200 prototypes," he said.
