✓ Correct! Pong, designed by Allan Alcorn at Atari (founded by Nolan Bushnell and Ted Dabney). The Sunnyvale bar Andy Capp’s reportedly called Atari to complain the prototype had broken; when Alcorn arrived, the cabinet was fine — the coin box was simply jammed full. Pong went on to sell over 8,000 cabinets and effectively created the consumer video-game industry. Bushnell’s earlier Computer Space (1971) is the very first commercial coin-op video game, but it sold poorly and didn’t spark the boom.

✗ Wrong. The answer is Pong. Space Invaders is Taito’s 1978 hit. Asteroids is Atari’s own 1979 vector-graphics smash. Computer Space (1971) is technically the first commercial coin-op video game ever — designed by Atari co-founder Nolan Bushnell — but it flopped at retail. Pong is the 1972 game that proved the industry could actually work.

✓ Correct! Atari, specifically the Atari 2600 (originally the VCS). Howard Scott Warshaw famously developed E.T. in five weeks to make a Christmas 1982 deadline; over 4 million unsold copies were eventually buried in the Alamogordo, New Mexico landfill in 1983 — later confirmed as real archaeology by a 2014 dig. The crash gutted the American console market until Nintendo launched the NES in 1985, with Japan taking over from there.

✗ Wrong. The answer is Atari (the 2600). Magnavox’s Odyssey was the very first home console (1972) but had been long-superseded by 1983. ColecoVision and Intellivision were 2600 competitors that also got hit by the crash, but the headline disasters — E.T. and the Pac-Man port — were Atari’s, and Atari was the dominant brand whose collapse defined the era.

✓ Correct! Super Mario Bros. (September 1985 in Japan as the Famicom version, October 1985 in North America bundled with the NES). Miyamoto and Takashi Tezuka’s 8-bit blueprint for the genre — running, jumping, scrolling, secrets — sold over 40 million copies and was the standard pack-in NES title (sometimes packed alongside Duck Hunt on the Zapper bundle). The Legend of Zelda came in 1986; Super Mario Bros. is the title that defined the launch.

✗ Wrong. The answer is Super Mario Bros. Donkey Kong (1981) is Miyamoto’s arcade breakthrough — and Mario’s actual debut as “Jumpman.” Duck Hunt was bundled with the Zapper-pack version of the NES alongside Super Mario Bros. The Legend of Zelda came a year later (1986). The headline NES launch title is Super Mario Bros.

✓ Correct! Minecraft — over 300 million copies sold, with Markus “Notch” Persson’s Mojang acquired by Microsoft for $2.5 billion in November 2014. The game launched in alpha in 2009, hit full release in November 2011, and has since shipped on every major platform from PC to Switch to phones to PlayStation. GTA V is the second-best-selling game ever (~200M+) and the most profitable entertainment product of all time. Tetris versions vary by counting method but together comfortably exceed 500M; the question specifies a single game, where Minecraft leads.

✗ Wrong. The answer is Minecraft. Tetris is technically larger across all versions combined but is fragmented across dozens of separately-counted SKUs. GTA V is the second-best-selling discrete game (~200M+) and the most profitable entertainment product ever made. Wii Sports moved 82M but mostly as a pack-in. The single best-selling game ever is Minecraft.

✓ Correct! Donkey Kong (1981). Nintendo of America had crates of unsold Radar Scope cabinets sitting in a New Jersey warehouse; Miyamoto’s pitch — a Popeye-inspired story about a giant ape and a damsel in distress — was retrofitted into the existing hardware. The game made $280 million in its first two years, single-handedly saved Nintendo of America, and gave the world both Donkey Kong and Mario (originally just called “Jumpman”). It also drove a Universal Studios trademark lawsuit over alleged King Kong similarity, which Nintendo won.

✗ Wrong. The answer is Donkey Kong. Mario Bros. is the 1983 arcade follow-up where Mario gets his name and his plumber brother Luigi. Popeye (1982) is Miyamoto’s next game — the IP he’d originally wanted for what became Donkey Kong. Galaga (1981) is by Namco, not Nintendo. Miyamoto’s breakout game is Donkey Kong.

✓ Correct! Nintendo. The two companies had jointly developed a SNES CD-ROM add-on (codenamed “Play Station,” with the space) for years. At CES 1991, Sony announced the partnership on day one; on day two, Nintendo’s Howard Lincoln walked on stage and revealed Nintendo had quietly switched to Philips. Sony executive Ken Kutaragi convinced his board to use the prototype to build their own standalone console. The result, three years later, was the PlayStation — which buried the SNES’s successor, the N64, in third place that generation. One of the most expensive corporate snubs in business history.

✗ Wrong. The answer is Nintendo. Sega had its own CD-ROM add-on (the Sega CD, 1991). Atari was a fading competitor. Panasonic eventually shipped the 3DO (1993), but Sony’s entry into hardware was specifically driven by the Nintendo partnership collapse at CES 1991 — one of the most consequential corporate breakups in the industry’s history.

✓ Correct! The original Xbox — Microsoft’s first home console, launched November 15, 2001 in North America. Microsoft acquired Bungie in June 2000 specifically to make Halo an Xbox-exclusive launch title (it had originally been pitched as a Mac/PC RTS). Halo: Combat Evolved sold over 5 million copies, became the Xbox’s system-seller, and made the franchise a permanent Microsoft pillar through Halo 2’s Xbox Live revolution and beyond.

✗ Wrong. The answer is the original Xbox. PlayStation 2 launched a year earlier (October 2000). The GameCube launched within days of the Xbox in November 2001 but never had Halo. The Dreamcast (1998) was discontinued in early 2001. Halo’s home is the Xbox — its existence as an exclusive is the entire reason Microsoft bought Bungie.

✓ Correct! Valve, founded in 1996 by ex-Microsoft executives Gabe Newell and Mike Harrington. Steam launched in September 2003 mainly as a way to deliver patches for Counter-Strike, with Half-Life 2 (2004) the first commercial release tied to it. Newell’s repeatedly-voiced philosophy — that piracy is fundamentally a service problem — turned Steam into the dominant PC platform and made Valve, a privately-held company, one of the most valuable per-employee firms in technology.

✗ Wrong. The answer is Valve. Blizzard runs Battle.net (Diablo, World of Warcraft, Hearthstone). id Software is the original Doom/Quake studio, now owned by Microsoft via the Bethesda/ZeniMax acquisition. Epic Games runs the competing Epic Games Store (launched 2018) alongside Fortnite and Unreal Engine. Steam — and Half-Life, Portal, Left 4 Dead, Counter-Strike, Dota 2 — is Valve.
