The Nintendo 64, often abbreviated as N64, is a home video game console that was developed and marketed by Nintendo. It is named in recognition of its 64-bit central processing unit (CPU). The console was released in multiple regions back in the mid-1990s and is considered a classic in the world of gaming.

Released in Japan in June 1996, and later in North America and Europe in September and March respectively, the Nintendo 64 was the successor to Nintendo's previous console, the Super Nintendo Entertainment System (SNES). The company's third home video console, it competed directly with the Sony PlayStation and the Sega Saturn during the fifth generation of video gaming.

Designed to appeal to a broader and more international audience than any of its predecessors, the N64 was marketed as a piece of sophisticated high-tech gaming equipment, aimed at teenagers and adults as well as children. Its games were released in cartridge format, as opposed to the compact disc format used by its main competitors at the time. This was a decision driven by concerns over piracy and faster loading times.

The Nintendo 64 is known for its high-profile exclusive games like "Super Mario 64", "The Legend of Zelda: Ocarina of Time", and "GoldenEye 007". Super Mario 64, one of the console's launch titles, is often hailed as one of the greatest games of all time. This is in part due to its pioneering of the 3D genre of gaming, and its utilisation of the console's analog stick.

Despite launching later than its competitors in the '90s, the Nintendo 64 managed to create a significant footprint in the gaming world, offering innovative features for the time, such as four-controller ports, that encouraged social, multiplayer gaming.

However, it is worthy to note that, the Nintendo 64, while enjoying considerable success, was not able to outperform the PlayStation in terms of sales. The high production costs of the cartridges, along with certain decisions made by Nintendo during its development, resulted in a smaller game library when compared to its rivals.

Today, the Nintendo 64 is a fondly remembered piece of gaming history. Its unique combination of innovative hardware, groundbreaking graphics, and a small but high-quality variety of games, has ensured its enduring appeal and a loyal fan base. Nintendo discontinued the 64 in 2002, but it lives on, particularly in the thriving market for retro gaming consoles and merchandising.
