Skype is unique in the internet industry. And its unique gene comes from its founders: Niklas Zennstroem and Janus Friis.
Those two guys are tough to get along well with. The destiny drew them together in the telecom company of TELE2, where they learned what telecommunication was. Then they wrote a shareware called Kazaa that gave all IDC and webmaster headaches.
You may never have used this software. It was a P2P downloading sharp tool, which could fill your hard disk up fully within one week.
Just the same as the famous Napster, the large records companies took the Kazza to the court. So Niklas Zennstroem and Janus Friis lived in seclusion for a period.
Kazaa was illegal but its technology was excellent. Those two guys who were familiar with the telecommunication naturally made use of this P2P technology in transmitting voice messages. Then Skype was born. According to Janus Friis Skype was a coinage from one sentence of the east European language, which means that communicating freely.
This miracle software can let you telephone on the network freely. At first this software had many bugs but was easy to use. Just like Kazza Skype spread on the internet like virus without any promotion. Those two used-to-be wanted criminals now become successful people in Silicon Valley.
