Skype
Skype is communications software whose purpose is to break down barriers to communication. With an Internet-connected device, families, friends and colleagues can get together for free with messaging, voice and video. At low cost, they can also call landlines or mobiles virtually anywhere in the world. Skype has recently introduced group video, allowing groups of more than two people to do things together whenever they're apart.
Founded in 2003 and based in Luxembourg, Skype is a division of Microsoft Corp. (NASDAQ: MSFT). Skype can be downloaded onto computers, mobile phones and other connected devices for free at www.skype.com.
