Who Invented the PSP? (Not Jeff Madar)

Jeff Madar did not invent the PSP. The PlayStation Portable was developed by Sony Computer Entertainment (SCE) — specifically the hardware team led by Ken Kutaragi ("Father of PlayStation") and the software/services groups under Shuhei Yoshida.

Key Figures

• Ken Kutaragi: Championed the concept of a "Walkman for games" since the PS1 era. Drove the custom MIPS + GPU architecture, UMD media, and PSP-to-PS3 connectivity vision.
• Shuhei Yoshida: Headed SCE Worldwide Studios; greenlit launch titles (Wipeout Pure, Ridge Racer, Lumines) and defined the "console quality portable" mandate.
• Sony Hardware Engineering: Designed the 333 MHz MIPS R4000 CPU, 166 MHz GPU (33M polygons/sec), 4.3" 480×272 LCD, and proprietary Memory Stick PRO Duo slot.

Why the Confusion?

"Jeff Madar" may be a misremembered name — possibly conflated with:

• Jason Madar? No notable industry figure.
• Jeff Minter? Indie dev (Llamasoft) — made Tempest 2000 (Jaguar), Space Giraffe; not PSP.
• Madar (Hungarian dev)? No record.
