A brief history on Skype

Skype is not the first P2P software to be made widely available via the Internet and to achieve mainstream status. Indeed, the people who founded Skype, Niklas Zennström and Janus Friis, are the same people who created the P2P file sharing program Kazaa, which is the most downloaded (at 363 million as of September 2004) software In the history of the Internet. Skype clearly has something of a\ pedigree.
Skype was founded in 2002, but the domain names Skype.com and Skype.net weren’t registered until April 2003. August 2003 saw the release of the first public beta, or trial, version of the Skype softphone (often also referred to as the Skype client). In June 2004, Skype introduced its first fee-based service, SkypeOut, which enables Skype users to call regular phone numbers all over the world at very low rates (as low as $0.021 per minute). SkypeIn, which is a fee-based service that allows people to call Skype users from regular phones, debuted in March 2005. Skype continues to add new features and services at a rapid pace.
