Background
The first commercially successful handheld game console was Nintendo's Game Boy, released in 1989. The original Game Boy featured a monochrome LCD screen and relied on cartridges. Later handhelds added color screens, integrated lighting, clamshell designs, and touchscreen controls. Popular handheld consoles over the years include the Game Boy Advance, Nintendo DS, PlayStation Portable, and Nintendo Switch.
There are now many handheld gaming PCs, Android gaming devices, and retro emulation consoles being produced by companies like Valve, Logitech, ASUS, Razer, and Analogue.
