a Yakuza clan had been creating them, and met with their leader to request they cease production. In response, the man said he would "suppress" Nakamura's competitors and make him Japan's largest video game developer. Nakamura declined, fearing it would lead to both the downfall of his company and the industry as a whole. As a counter-measure, Nakamura requested additional Breakout units from Atari as soon as possible. Nakamura flew to London to meet with Bushnell at the Music Operators Association (MOA) tradeshow to discuss the issue — Nakamura claimed that Bushnell was drunk and unable to listen to him, leading to him having his company produce Breakout units without Atari's permission. Breakout was an unprecedented success for his company, becoming one of the most successful video game manufacturers in Asia alongside Sega and Taito. This would lead to Atari taking legal action in the 1970s. Nakamura's company was renamed to Namco in 1977, an acronym of their older name. Nakamura would also open up a division in the United States as requested by Nakajima, Namco America, located a few blocks away from the Atari headquarters in Sunnyvale, California — Nakajima would become the president of the company. Arcade successes and Atari Games Impressed by the success of the Atari Japan acquisition, Nakamura was interested in his company creating his own arcade games in-house. He purchased a surplus amount of PDA-80 microcomputers from NEC and instructed his employees to analyze the hardware to intentionally create video games. Namco's first in-house game was Gee Bee (1978), designed by Toru Iwatani. Namco's first major success in arcades was Galaxian (1979), credited as one of the first video games to use RGB. The game's success led to Nakamura approaching Midway Games to release some of their games in the United States, which they agreed to. Pac-Man (1980) became Namco's biggest success, selling over 400,000 arcade units in the United States alone and becoming one of the highest-grossing video games of all time. It was designed by one of Namco's new hires, Toru Iwatani, with Nakamura suggesting the game be named after the sound the character made while eating, "paku paku". In a 1983 interview, Nakamura said that he "never thought it would be this big". Under Nakamura's leadership, Namco would produce several successful games throughout the 1980s, including Galaga (1981), Ms. Pac-Man (1982), Dig Dug (1982), Pole Position (1982), Xevious (1983) and The
