Skype was developed by a group of childhood friends and Scandinavian entrepreneurs in Estonia, only 12 years after the collapse of the Soviet Union.
Skype was the first app to provide voice calls over the Internet as an alternative to traditional phone calls.
Skype quickly gained millions of users and was known for its simplicity and ease of use.
Skype's success led to its acquisition by eBay for $2.6 billion, but the expected synergies did not materialize.
Microsoft acquired Skype in 2011 for $8.5 billion, but it struggled to capitalize on the app's potential and faced competition from other communication platforms like WhatsApp and Zoom.
