Since it was released in March 2015, Discord’s popularity has increased especially among gamers, given that it is free, simple, multiplatform, and innovative. As of July 2016, more than 11 million people have used it.
Any Discord user can create a server, or group, in less than 10 seconds. Most of the groups on Discord are gamer gatherings (teams, guilds, clans) that use the VoIP service to communicate (via chat or voice) whether gaming or not.
