Skype 5.0 arrived in 2010 with a refreshed interface and a set of crisp alert tones, and the incoming call ringtone quickly became one of the most heard sounds on personal computers. Long after Skype faded from daily use, the tone survived as a shorthand for an incoming video call in memes and reaction videos, the same way the Discord call tone is used today. Creators drop it into skits, fake-call pranks and nostalgia compilations whenever a ringing phone or laptop screen needs instant recognition.
