Nintendo Pro Wireless Controller for Nintendo Switch

Nintendo Co., Ltd. is a Japanese multinational video game company headquartered in Kyoto. It develops, publishes, and releases both video games and video game consoles.

The history of Nintendo began when craftsman Fusajiro Yamauchi founded the company to produce handmade hanafudaplaying cards. After venturing into various lines of business and becoming a public company, Nintendo began producing toys in the 1960s, and later video games. Nintendo developed its first arcade games in the 1970s, and distributed its first system, the Color TV-Game, in 1977. The company became internationally dominant in the 1980s after the arcade release of Donkey Kong (1981) and the Nintendo Entertainment System, which launched outside of Japan alongside Super Mario Bros. in 1985.

Since then, Nintendo has produced some of the most successful consoles in the video game industry, including the Game Boy (1989), the Super Nintendo Entertainment System (1991), the Nintendo DS (2004), the Wii (2006), and the Nintendo Switch (2017). It has created or published numerous major franchises, including Mario, Donkey Kong, The Legend of Zelda, Animal Crossing, and Pokémon. The company's mascot, Mario, is among the most famous fictional characters, and Nintendo's other characters—including Luigi, Donkey Kong, Samus, Link, Kirby, and Pikachu—have attained international recognition. Several films and a theme park area based on the company's franchises have been created.

Nintendo's game consoles have sold over 836 million units worldwide as of March 2023, and 5.6 billion individual games have been sold. The company has numerous subsidiaries in Japan and worldwide, in addition to second-party developers including HAL Laboratory, Intelligent Systems, Game Freak, and The Pokémon Company. It is one of the wealthiest and most valuable companies in the Japanese market.

Pro is an abbreviation meaning "professional".

In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. The most common type of switch is an electromechanical device consisting of one or more sets of movable electrical contacts connected to external circuits. When a pair of contacts is touching current can pass between them, while when the contacts are separated no current can flow.

Switches are made in many different configurations; they may have multiple sets of contacts controlled by the same knob or actuator, and the contacts may operate simultaneously, sequentially, or alternately. A switch may be operated manually, for example, a light switch or a keyboard button, or may function as a sensing element to sense the position of a machine part, liquid level, pressure, or temperature, such as a thermostat. Many specialized forms exist, such as the toggle switch, rotary switch, mercury switch, push-button switch, reversing switch, relay, and circuit breaker. A common use is control of lighting, where multiple switches may be wired into one circuit to allow convenient control of light fixtures. Switches in high-powered circuits must have special construction to prevent destructive arcing when they are opened.

Wireless communication (or just wireless, when the context allows) is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth, or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications involve other electromagnetic phenomena, such as light and magnetic or electric fields, or the use of sound.

The term wireless has been used twice in communications history, with slightly different meanings. It was initially used from about 1890 for the first radio transmitting and receiving technology, as in wireless telegraphy, until the new word radio replaced it around 1920. Radio sets in the UK and the English-speaking world that were not portable continued to be referred to as wireless sets into the 1960s. The term wireless was revived in the 1980s and 1990s mainly to distinguish digital devices that communicate without wires, such as the examples listed in the previous paragraph, from those that require wires or cables. This became its primary usage in the 2000s, due to the advent of technologies such as mobile broadband, Wi-Fi, and Bluetooth.

Wireless operations permit services, such as mobile and interplanetary communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to telecommunications systems (e.g. radio transmitters and receivers, remote controls, etc.) that use some form of energy (e.g. radio waves and acoustic energy) to transfer information without the use of wires. Information is transferred in this manner over both short and long distances.
