Skype was launched in 2003 and acquired by Microsoft in 2011, becoming one of the first widely used apps for free voice and video calls over the internet. Skype 8 arrived as a major redesign in 2017, with a refreshed interface and its own incoming call ring. As Skype faded from everyday use, the tone survived online as a nostalgic sound effect, shared on soundboards and in meme edits. Creators often compare it to a discord call sound from a newer generation of chat apps.
