Skype was launched in 2003. The mix of integrated services is increasing over time, and as of 2012 they provide:
- Voice connections. These are transferred over the internet as voice packets, or VoIP. Calls may also be made to and from conventional telephones
- Low resolution video. This uses inexpensive webcams, allowing participants seeing each other as they talk
- Screen sharing
- Instant messaging and presence information
- File transfers
