Aurora is one of the original text tones that shipped with the iPhone, the short chime users could assign to incoming SMS and iMessage alerts. Because it lived on millions of phones, the sound became instantly recognisable shorthand for a new message, and editors began ripping it for sketches, memes and YouTube videos that fake a phone receiving texts. Its popularity endures because the brain is wired to notice phone pings, much like a Discord notification or a simple ding sound effect cuts through a scene.
