History

Sony first announced development of the PlayStation Portable at a press conference before E3 2003.^[23] Although mock-ups of the system were not present at the press conference or E3,^[23] Sony did release extensive technical details regarding the new system.^[24] Then-CEO of Sony Computer Entertainment Ken Kutaragi called the device the "Walkman of the 21st Century" in a reference to the console's multimedia capabilities.^[25] Several gaming websites were impressed by the handheld's computing capabilities and looked forward to the system's potential as a gaming platform.^[8][23][26]

The first concept images of the PlayStation Portable appeared in November 2000 at the Sony Corporate Strategy Meeting and showed a PSP with flat buttons and no analog stick.^[27] Although some expressed concern over the lack of an analog joystick,^[28] these fears were allayed when the PSP was officially unveiled at the Sony press conference during E3 2004.^[29] In addition to announcing more details about the system and its accessories,^[30] Sony also released a list of 99 developer companies that had pledged support for the new handheld.^[31] Several PSP game demos, such as Konami's Metal Gear Acid and SCE Studio Liverpool's Wipeout Pure were also shown at the conference.
