Skype launched in 2003 and became the default video calling app for years, so its interface sounds were heard by millions daily. This drop tone was part of that familiar set, alongside its ringtone and notification chime. After Microsoft bought Skype in 2011 the sound stayed in use through many updates. As calling moved to apps like a Discord call, the Skype blip survived online as a nostalgic meme sound, reused in videos to mean someone has been cut off, rejected, or has left the chat.
