Pac-Land (パックランド, Pakku-Rando) is an entry in the Pac-Man series of arcade video games, released into arcades by Namco, and its American distributor Bally Midway (now Midway Games), in August 1984. It was the first Namco arcade game to use the then-new arcade system later titled as Namco Pac-Land. Pac-Land features parallax scrolling for some of the background elements, a feature that would not become commonplace until the 16-bit console era began much later.

Pac-Man (パックマン, Pakkuman?) is an arcade game developed by Namco and first released in Japan on May 22, 1980. It was licensed for distribution in the United States by Midway and released in October 1980. Immensely popular from its original release to the present day, Pac-Man is considered one of the classics of the medium, virtually synonymous with video games, and an icon of 1980s popular culture. Upon its release, the game—and, subsequently, Pac-Man derivatives—became a social phenomenon that sold a large amount of merchandise and also inspired, among other things, an animated television series and a top-ten hit single. When Pac-Man was released, the most popular arcade video games were space shooters, in particular Space Invaders and Asteroids. The most visible minority were sports games that were mostly derivatives of Pong. Pac-Man succeeded by creating a new genre and appealing to both genders. Pac-Man is often credited with being a landmark in video game history, and is among the most famous arcade games of all time. It is also one of the highest-grossing video games of all time, having generated more than $2.5 billion in quarters by the 1990s. The character has appeared in more than 30 officially licensed game spin-offs, as well as in numerous unauthorized clones and bootlegs. According to the Davie-Brown Index, Pac-Man has the highest brand awareness of any video game character among American consumers, recognized by 94 percent of them. Pac-Man is one of the longest running video game franchises from the golden age of video arcade games. It is part of the collection of the Smithsonian Institution in Washington, D.C. and of New York's Museum of Modern Art.
