Skype was founded in 2003 by Niklas Zennström and Janus Friis. Skype created a little piece of software that makes communicating with people around the world easy and fun. With Skype you can say hello or share a laugh with anyone, anywhere. And if both of you are on Skype, it’s free.
Skype is available in 28 languages and is used in almost every country around the world. Skype generates revenue through its premium offerings such as making and receiving calls to and from landline and mobile phones, as well as voicemail and call forwarding. Skype, based in Luxembourg, has relationships with a growing network of hardware and software providers and is an eBay company.

The main difference between Skype and VoIP clients is that Skype operates on a peer-to-peer model, rather than the more traditional server-client model. The Skype user directory is entirely decentralized and distributed among the nodes in the network, which means the network can scale very easily to large sizes (currently about 240 million users) without a complex and costly centralized infrastructure.
Skype Limited faces challenges from two main directions. Firstly it faces legal challenges to its intellectual property and secondly it faces political pressures by governments wishing to control the telecommunications systems of their respective countries.

Skype is one of many companies (others include AOL, Google, Microsoft, Yahoo, Cisco) which have cooperated with the Chinese government in implementing a system of Internet censorship in the People's Republic of China. Niklas Zennström, chief executive to Skype, told reporters that its joint venture partner in China is operating in compliance with domestic law. "TOM Online had implemented a text filter, which is what everyone else in that market is doing," said Zennström. "Those are the regulations," he said. "I may like or not like the laws and regulations to operate businesses in the UK or Germany or the US, but if I do business there I choose to comply with those laws and regulations. I can try to lobby to change them, but I need to comply with them. China in that way is not different."
Since late September, users in China trying to download the Skype software are redirected to the TOM site from which a modified Chinese version can be downloaded. Activists in China are warning about the possibility that TOM's versions have or will have more trojan capability.
