Apple's iPhone, first released in 2007, made its short alert tones part of everyday life as smartphones spread around the world. The familiar chime quickly moved beyond the phone itself, appearing in YouTube videos, TikTok edits, and reaction clips whenever a creator wanted an instant, recognisable signal for a new message. Like a Discord notification, it works because listeners already associate the sound with something arriving on their device. Its short length and clean tone keep it useful for comedy, pranks, and short-form content years after it first became familiar.
