Nintendo introduced Amiibo in 2014 as collectible figures containing an NFC chip that could be tapped against a Wii U GamePad or Nintendo Switch controller to unlock characters, items, and bonuses in compatible games. The figures quickly became popular with collectors and players of Super Smash Bros. and The Legend of Zelda, and clips of scans, unboxings, and reactions spread across YouTube and social media. As a short game notification, the sound is still used today to signal a successful scan, a new addition to a collection, or a playful Nintendo reference in gaming videos.
