An Internet telephone and video calling service from Skype Technologies S.A.R.L., Luxembourg City, Luxembourg (, a division of Microsoft. Being software based, calls from Skype subscribers originate from their computers or mobile devices, and if the recipient is using a computer or mobile, voice and video calls are free. Access to regular telephones is also available. For outgoing calls, users can dial a landline or cellphone for a low per-minute or monthly charge, and subscribers can obtain a Skype number to receive calls from landlines and cellphones worldwide.

In 2010, Skype introduced its group video calling service that lets five people have a videoconference.

Explosive Growth
Introduced in 2004, within a year, more than a hundred million people downloaded the software. In the fall of 2005, Skype claimed 40 million active users and was acquired by eBay for USD $2.6 billion. By late 2008, an average of 10 million users were using Skype simultaneously. Skype was acquired by private investors a year later with eBay retaining a major equity position. In 2011, Microsoft bought Skype and partnered with Facebook to allow its members to make video calls.

Rather than using standard voice over IP (VoIP) protocols such as SIP and H.323, Skype uses proprietary protocols that incorporate a peer-to-peer architecture. If Skype cannot make a direct connection from one user to the other, it may elicit one of its users who has the Skype application loaded to become a "supernode" and relay the call. Only a fraction of the millions of Skype users become supernodes at any given time. See Skype for Business, supernode and softphone.
