"The PSP was one of the first machines that had the hardware to allow you to play 'proper console games' on the go": Developers celebrate 20 years of Sony's handheld

When the tenth anniversary of the PlayStation rolled around on 3 December 2004, Sony was on top of the world. Its original machine had transformed the business, and the PlayStation 2 had only extended its market dominance. What’s more, the company was just days away from launching the PlayStation Portable, its first foray into the handheld console market – a field that had been dominated by Nintendo and its Game Boy family of consoles since 1989. Of course, Nintendo had seen off no shortage of pretenders to the throne over the prior 15 years, but Sony had already overthrown market leaders once and nobody with an ounce of sense was willing to downplay the potential for the company to do it again.

Sony announced the PSP – better known by its initialisation than its full name, even then – at E3 2003. Ken Kutaragi promised that the PSP would inhabit “a world where all kinds of entertainment, like games, music, movies are going to be fused together”, pitching it as “the Walkman of the 21st century”. The only piece of physical hardware shown was a prototype of the system’s proprietary storage media, the Universal Media Disc – a 60mm dual-layer optical disc contained in a plastic housing, offering a high storage capacity of 1.8GB. A concept image of the console itself later surfaced in November 2003 – a sleek, stylish black device with a look relatively similar to the final design, albeit with a totally flat d-pad and buttons and no apparent analogue input or shoulder buttons.
