The level-up jingle comes from the Pokemon video game series, created by Game Freak and published by Nintendo, which began in Japan in 1996. Across the mainline games, a short fanfare plays whenever a Pokemon earns enough experience to grow stronger, making it one of the most recognisable sounds in gaming. As gameplay clips, streams and edits spread online, the jingle moved beyond the games into memes and short-form video, where it now signals any kind of progress, improvement or well-earned reward.
