Pokémon Phenomenon

How a Game Boy game became a worldwide craze

Pokémon began as a quiet Game Boy release in Japan in February 1996. Within two years the games, the trading cards and the TV cartoon had made it Japan's biggest craze, big enough for a single cartoon episode to send hundreds of children to hospital in December 1997. America followed in 1998–99, with a million-selling card game, a feature film and a Burger King promotion that ended in a recall, and Britain in 1999–2000, where schools banned the cards. Pokémon GO revived it on phones in 2016.

“Pokémon became the world’s biggest videogame by a process of systematic and calculating media saturation,” Edge wrote in 2003, setting up the usual explanation of the craze. Then it knocked it down: “Except of course, that’s not how it happened. The game came first, and everything that followed was born out of the fervour that it inspired.”

The game was Game Freak’s Pocket Monsters, which went on sale in Japan in February 1996 with little fuss. The cards, the cartoon, the films and the toys followed it, country by country, and each time the same pattern played out: a craze among children, then alarm among adults. This entry follows that craze. The games themselves are covered in Pokémon and Pokémon Red & Blue.

Fast facts

  • Began: Pocket Monsters Red and Green, Game Boy, Japan, 27 February 1996.
  • Spread: the trading card game (Japan, October 1996), the TV series (TV Tokyo, April 1997), the first film (Japan, July 1998; North America, November 1999).
  • Waves: Japan 1996–97; North America 1998–99; Britain 1999–2000; Pokémon GO, 2016.
  • Scale by March 2026: more than 515 million units of Pokémon software shipped, more than 85 billion cards printed, and the TV series shown in more than 190 countries and regions (The Pokémon Company).

Japan, 1996–97

The game arrived quietly and then kept selling. The Pokémon Company launched the trading card game in October 1996, and in April 1997 TV Tokyo began showing the cartoon. At Nintendo’s Space World show in November 1997, Edge reported, Pocket Monsters had been the best-selling game in Japan that year. By the end of December, Edge wrote, the monsters were “easily Japan’s most popular Christmas present this year by a substantial margin”, two songs from the show were in the Christmas Top 40, and around ¥400 billion (£3.19 billion) of Pocket Monsters merchandise had been sold. In the spring of 1998 Nintendo Power counted more than 600 Pokémon products in Japanese shops.

Then came the scare. On 16 December 1997 TV Tokyo showed an episode called “Computer Warrior Porygon”, in which the characters travel inside a computer. About twenty minutes in, an explosion was followed by flashing red lights, and children watching across Japan began to fall ill. The British magazines’ figures differ: Edge reported that about 600 children had an epileptic reaction and about 120 stayed in hospital overnight, while Computer and Video Games said 729 children had been taken to hospital and 208 kept in. Both blamed photosensitive epilepsy, set off by the flashing. TV Tokyo held an emergency press conference and began an investigation, several stations said they would not show the cartoon again, and Nintendo’s share price fell the next day. Edge expected no lasting harm to Nintendo, and noted that the series had already been sold to American television, where it would be shown “with the offending scene cut out”.

North America, 1998–99

Nintendo of America brought Pokémon over all at once. The cartoon started on American television on 7 September 1998, ahead of the Red and Blue games at the end of the month, and Nintendo opened the campaign as an “invasion” that started in Topeka, Kansas. The Pokémon Red & Blue entry tells that story.

The cards took off next. Wizards of the Coast published the trading card game in English, and by September 1999 Nintendo Power reported that it had sold more than a million copies in North America and that “Pokémaniacs want to unwrap all the booster packs they can find”. The Jungle expansion added 64 more cards. A month later the magazine was warning readers about fakes: “when a craze gets big enough, people with the ethics of Team Rocket decide to try to take advantage of it.” Genuine goods, it explained, carried the copyright line of Nintendo, Creatures and Game Freak.

Pokémon: The First Movie opened across North America on 12 November 1999, with a short, Pikachu’s Vacation, before the main feature, Mewtwo Strikes Back. Burger King promoted it with 57 toys and 151 trading cards to collect from its children’s meals, and Edge reported that the company’s Pokémon website had 1.3 million hits in its first six hours. The toys came in plastic Poké Balls, and the balls were dangerous. In December 1999 a 13-month-old girl suffocated when half of one sealed over her nose and mouth. Burger King and the US Consumer Product Safety Commission recalled more than 25 million of the balls on 27 December, and in January 2000, after a four-month-old boy died the same way, they urged parents again to destroy them. When Burger King brought the promotion back in 2000, N64 Magazine noted, the toys came in small plastic bags.

The craze reached the sky as well. All Nippon Airways had painted three of its planes with Pokémon, and in September 1999 Edge reported that the airline had taken them international, on a five-days-a-week service between Tokyo and San Francisco, with Pokémon goods on sale duty-free.

Britain, 1999–2000

The games reached Britain in October 1999, at £24.99, and the counterfeiters were already there. Computer and Video Games warned that pirated Pokémon toys and cards were arriving, and quoted Nintendo’s licensing agent: “There’s little official Pokémon merchandise this year.”

In the spring of 2000 the cards reached the playground. N64 Magazine reported in June that, according to the BBC’s news website, a growing number of schools were banning them. A packet of eleven cost £2.25, but the rarest cards could be worth £30, and “anything up to £300 on Internet auctions”. Teachers worried about “aggressive trading” in school. That spring Pokémon: The First Movie opened in British cinemas and went straight to number one, knocking Lake Placid off the top. Edge later collected the year’s stranger news stories, among them a Californian school that paid a pupil $1,500 in compensation after losing the Pokémon cards it had confiscated, and an eight-year-old in Hampshire who offered his baby sister on a radio swap-shop in exchange for a rare Vaporeon card.

After the craze

By 2003 Edge could write that “Pokéfever may have abated”, but Game Freak kept making a new pair of games every few years, and each pair found new players. In July 2016 Pokémon reached phones with Niantic’s Pokémon GO. Looking back at the decade, Wireframe listed it among the events of 2016 as the game that “turns mobile phones into a monster-catching app”. By the end of March 2026 The Pokémon Company counted more than 515 million units of Pokémon software shipped and more than 85 billion trading cards printed.
