Skype launched in 2003 and became the default way many people made free voice and video calls over the internet during the 2000s and 2010s. Its default incoming call melody was heard in homes, offices and gaming setups worldwide, so the short loop became inseparable from the experience of waiting for a friend to pick up. After Microsoft bought Skype in 2011 the tone remained familiar to a new generation of users. Today the ringtone survives online as a nostalgic meme sound, used long after regular Skype calls faded.
