The theme comes from the Nintendo Wii, the home console Nintendo released in 2006, where it played on the system menu that players saw every time they turned the machine on. As the Wii became a cultural touchstone, clips of its calm, cheerful menu music spread across YouTube, TikTok and meme edits, often detached from gameplay itself. It remains popular because it instantly signals a specific era of gaming, making it a quick shorthand for nostalgia, innocence and laid-back family play in modern short-form videos.
