When you think about chatting to someone overseas you naturally turn to Skype. Why use the landline to make those international phone calls when you can not only chat to your fiends and family but also see them?
In August 2013 Skype turned 10 years old and it has come a long way since its first released back in August 2003
Skype was originally developed by Estonian, Danish and Swedish developers who had also originally developed the peer to peer file sharing network Kazaa. Skype was the first hybrid peer-to-peer and client–server systems which makes use of background processing on computers running Skype software, and this is reflected in Skype’s original proposed name of Sky Peer-to-Peer
Over the past 10 years, Skype has changed hands several times. From eBay Inc. who bought Skype for approximately $2.5 billion in 2005 to Silver Lake, Andreessen Horowitz and the Canada Pension Plan Investment Board acquisition who purchased Skype for $1.9 billion when eBay sold 65% in 2009. In 2011, Microsoft had purchased Skype for $8.5 billion which it invested heavily in even phasing out its long-standing Windows Live Messenger.
Microsoft has revealed that Skype has 300 million connected users and a third of all international telephone calls now go through Skype. Skype users have spent over 1.4 trillion minutes using the service over past 10 years which translates into 2.6 million years of conversations.
