Created in August of 2003 by the developers Ahti Heinla, Priit Kasesalu, and Jaan Tallinn, Janus Friis and Niklas Zennström, this freemium voice-over-IP service and instant messaging app grew with tremendous pace, mostly because it managed to give people unique opportunity to call landline and mobile phone numbers directly from their PC. As years went on this VoIP focus remained strong, but other elements of the site grew, enabling hundreds of millions of people easy way to establish text, audio and video chats between wide variety of supported hardware devices and operating systems (Windows, Linux, Mac, OS X, iOS, Android, BlackBerry OS, Symbian, and many home and portable consoles).
All of those features can be accessed on PC even on very old configurations, widening the possible user base to almost all modern PC users. As of end of 2011, Skype was used by over 630 million people, and in 2012 this app was purchased by the software giant Microsoft who further more enabled Skype to become part of their entire OS ecosystem.
