pinball industry reached a peak of 200,000 machine sales and $2.3 billion revenue in 1979, which had declined to 33,000 machines and $464 million in 1982. In comparison, the best-selling arcade games of the golden age, Space Invaders and Pac-Man, had each sold over 360,000 and 400,000 cabinets, respectively, with each machine costing between $2000 and $3000 (specifically $2400 in Pac-Man's case). In addition, Space Invaders had grossed $2 billion in quarters by 1982, while Pac-Man had grossed over $1 billion by 1981 and $2.5 billion by the late 1990s. In 1982, Space Invaders was considered the highest-grossing entertainment product of its time, with comparisons made to the then highest-grossing film Star Wars, which had grossed $486 million, while Pac-Man is today considered the highest-grossing arcade game of all time. Many other arcade games during the golden age also had hardware unit sales at least in the tens of thousands, including Ms. Pac-Man with over 115,000 units, Asteroids with 70,000, Donkey Kong with over 60,000, Defender with 55,000, Galaxian with 40,000, Donkey Kong Junior with 35,000, Mr. Do! with 30,000, and Tempest with 29,000 units. A number of arcade games also generated revenues (from quarters) in the hundreds of millions, including Defender with more than $100 million in addition to many more with revenues in the tens of millions, including Dragon's Lair with $48 million and Space Ace with $13 million. The most successful arcade game companies of this era included Taito (which ushered in the golden age with the shooter game Space Invaders and produced other successful arcade action games such as Gun Fight and Jungle King), Namco (the Japanese company that created Galaxian, Pac-Man, Pole Position and Dig Dug) and Atari (the company that introduced video games into arcades with Computer Space and Pong, and later produced Asteroids). Other companies such as Sega (who later entered the home console market against its former arch rival, Nintendo), Nintendo (whose mascot, Mario, was introduced in 1981's Donkey Kong as "Jumpman"), Bally Midway Manufacturing Company (which was later purchased by Williams), Cinematronics, Konami, Centuri, Williams and SNK also gained popularity around this era. During this period, Japanese video game manufacturers became increasingly influential in North America. By 1980, they had become very influential through licensing their games to American manufacturers. Jonathan Greenberg of Forbes predicted in early 1981 that Japanese companies would eventually dominate the North American video game industry, as
