History of Nintendo
In 1972, the first commercially available video game console, the Magnavox Odyssey, had a light gun accessory, the Shooting Gallery. This was the first involvement of Nintendo in video games. According to Martin Picard in the "International Journal of Computer Game Research": "in 1971, Nintendo had -- even before the marketing of the first home console in the United States -- an alliance with the American pioneer Magnavox to develop and produce optoelectronic guns for the Odyssey (released in 1972), since it was similar to what Nintendo was able to offer in the Japanese toy market in 1970s".
Pac-Man
The game is regarded as one of the most influential video games of all time: its title character was the first original gaming mascot, the game established the maze chase game genre, it demonstrated the potential of characters in video games, it increased the appeal of video games with female audiences, and it was gaming's first broad licensing success. It was the first video game with power-ups, and the individual ghosts have deterministic artificial intelligence which reacts to player actions. It is often cited as the first game with cutscenes, in the form of brief comical interludes about Pac-Man and Blinky chasing each other, though "Space Invaders Part II" employed a similar style of between-level intermissions in 1979.
