The Sony PSP boot sound comes from the PlayStation Portable, Sony's handheld console first released in Japan in 2004 and in North America and Europe in 2005. The short startup jingle played every time the system was switched on, becoming closely linked to portable gaming in the mid-2000s. As clips of the console spread on video platforms, the sound became a shorthand for nostalgia, retro technology and gaming culture. It remains popular today because it instantly recalls a specific era of handheld play, even for viewers who never owned the device.
