Here’s a little blast from the past. In this February 1998 issue of UK magazine Computer and Video Games, I found an article about that Porygon episode of Pokemon that caused some kids in Japan to have seizures. We know now that it was caused by rapid flashes of red and blue lights from one of Pikachu’s attacks (read more here), but this article was written before they knew what sent so many kids to the hospital.
It’s interesting because Japanese TV networks started banning the show in response, and Tokyo TV threatened to cancel it outright if the cause wasn’t determined. Imagine a world where the Pokemon anime ended in the middle of its first season and never came back!
