Handheld game console in the context of "Nintendo Switch"

A smartphone is a mobile device that combines the functionality of a traditional mobile phone with advanced computing capabilities. It typically has a touchscreen interface, allowing users to access a wide range of applications and services, such as web browsing, email, and social media, as well as multimedia playback and streaming. Smartphones have built-in cameras, GPS navigation, and support for various communication methods, including voice calls, text messaging, and internet-based messaging apps. Smartphones are distinguished from older-design feature phones by their more advanced hardware capabilities and extensive mobile operating systems, access to the internet, business applications, mobile payments, and multimedia functionality, including music, video, gaming, radio, and television.

Smartphones typically feature metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, various sensors, and support for multiple wireless communication protocols. Examples of smartphone sensors include accelerometers, barometers, gyroscopes, and magnetometers; they can be used by both pre-installed and third-party software to enhance functionality. Wireless communication standards supported by smartphones include Wi-Fi, Bluetooth, Hotspots and satellite navigation. By the mid-2020s, manufacturers began integrating satellite messaging and emergency services, expanding their utility in remote areas without reliable cellular coverage. Smartphones have largely replaced personal digital assistant (PDA) devices, handheld/palm-sized PCs, portable media players (PMP), point-and-shoot cameras, camcorders, and, to a lesser extent, handheld video game consoles, e-reader devices, pocket calculators, and GPS tracking units.

A video game console is an electronic device that outputs a video signal or image to display a video game that can typically be played with a game controller. These may be home consoles, which are generally placed in a permanent location connected to a television or other display devices and controlled with a separate game controller, or handheld consoles, which include their own display unit and controller functions built into the unit and which can be played anywhere. Hybrid consoles combine elements of both home and handheld consoles.

Video game consoles are a specialized form of home computer geared towards video game playing, designed with affordability and accessibility to the general public in mind, but lacking in raw computing power and customization. Simplicity is achieved in part through the use of game cartridges or other simplified methods of distribution, easing the effort of launching a game. However, this leads to ubiquitous proprietary formats that create competition for market share. More recent consoles have shown further confluence with home computers, making it easy for developers to release games on multiple platforms. Further, modern consoles can serve as replacements for media players with capabilities to play films and music from optical media or streaming media services.

In the history of video games, the first generation era refers to the video games, video game consoles, and handheld video game consoles available from 1972 to 1983. Notable consoles of the first generation include the Odyssey series (excluding the Magnavox Odyssey 2), the Atari Home Pong, the Coleco Telstar series and the Color TV-Game series. The generation ended with the Computer TV-Game in 1980 and its following discontinuation in 1983, but many manufacturers had left the market prior due to the market decline in the year of 1978 and the start of the second generation of video game consoles.

Most of the games developed during this generation were hard-wired into the consoles and unlike later generations, most were not contained on removable media that the user could switch between. Consoles often came with accessories and cartridges that could alter the way the game played to enhance the gameplay experience as graphical capabilities consisted of simple geometry such as dots, lines or blocks that would occupy only a single screen. First generation consoles were not capable of displaying more than two colours until later in the generation, and audio capabilities were limited with some consoles having no sound at all.

A mobile game is a video game that is typically played on a mobile device. The term also refers to all games that are played on any portable device, including from mobile phone (feature phone or smartphone), tablet, PDA to handheld game console, portable media player or graphing calculator, with and without network availability.The earliest known game on a mobile phone was a Tetris variant on the Hagenuk MT-2000 device from 1994.

In 1997, Nokia launched Snake. Snake, which was pre-installed in most mobile devices manufactured by Nokia for a couple of years, has since become one of the most played games, at one point found on more than 350 million devices worldwide. Mobile devices became more computationally advanced allowing for downloading of games, though these were initially limited to phone carriers' own stores. Mobile gaming grew greatly with the development of app stores in 2008, such as the iOS App Store from Apple. As the first mobile content marketplace operated directly by a mobile-platform holder, the App Store significantly changed the consumer behaviour and quickly broadened the market for mobile games, as almost every smartphone owner started to download mobile apps.

Examples of smartphone sensors include accelerometers, barometers, gyroscopes, and magnetometers; they can be used by both pre-installed and third-party software to enhance functionality. Wireless communication standards supported by smartphones include LTE, 5G NR, Wi-Fi, Bluetooth, and satellite navigation. By the mid-2020s, manufacturers began integrating satellite messaging and emergency services, expanding their utility in remote areas without reliable cellular coverage. Smartphones have largely replaced personal digital assistant (PDA) devices, handheld/palm-sized PCs, portable media players (PMP), point-and-shoot cameras, camcorders, and, to a lesser extent, handheld video game consoles, e-reader devices, pocket calculators, and GPS tracking units.

A portable media player (PMP) or digital audio player (DAP) is a portable consumer electronics device capable of storing and playing digital media such as audio, images, and video files. Normally, they refer to small, battery-powered devices utilising flash memory or a hard disk for storing various media files. MP3 players has been a popular alternative name used for such devices, even if they also support other file formats and media types other than MP3 (for example AAC, FLAC, WMA).

Generally speaking, PMPs are equipped with a 3.5 mm headphone jack which can be used for headphones or to connect to a boombox, home audio system, or connect to car audio and home stereos wired or via a wireless connection such as Bluetooth, and some may include radio tuners, voice recording and other features. In contrast, analogue portable audio players play music from non-digital media that use analogue media, such as cassette tapes or vinyl records. As devices became more advanced, the PMP term was later introduced to describe players with additional capabilities such as video playback (they used to also be called "MP4 players"). The PMP term has also been used as an umbrella name to describe any portable device for multimedia, including physical formats (such as portable CD players) or handheld game consoles with such capabilities.

The Game Boy is a handheld game console developed by Nintendo, launched in the Japanese home market on April 21, 1989, followed by North America later that year and other territories from 1990 onwards. Following the success of the Game & Watch single-game handhelds, Nintendo developed the Game Boy to be a portable console, with interchangeable cartridges. The concept proved highly successful, and the Game Boy line became a cultural icon of the 1990s and early 2000s.

The Game Boy was designed by the Nintendo Research & Development 1 team, led by Gunpei Yokoi and Satoru Okada. The device features a dot-matrix display, a D-pad, four game buttons, a single speaker, and uses Game Pak cartridges. Its two-toned gray design included black, blue, and magenta accents, with softly rounded corners and a distinctive curved bottom-right edge. At launch in Japan it was sold as a standalone console, but in North America and Europe it came bundled with the wildly popular Tetris which fueled sales.
