One of the most common problems when playing popular online games is live chatting over the Internet. Some live chatting services require players to share multiple IP addresses to make calls, while others (such as Skype or TeamSpeak, TeamTalk) take up a lot of system resources. That led to the birth of Discord, a more user-friendly chat software based on modern technology.

Skype is currently the world's most popular free HD instant messaging software (and VoIP) for all kinds of desktop and mobile platforms. Low system resource requirement, high-quality voice communication and high stability have won its hundreds of millions of users around the world. After acquired by Microsoft in 2011, it became an independent department of Microsoft. And in 2013, if finally replaced Microsoft's own instant messaging tool MSN. In 2014, it released an embedded web version.
