Shoutcast

Shoutcast (formerly SHOUTcast) is a service for streaming media over the internet to media players, using its own cross-platform proprietary software. It allows digital audio content, primarily in MP3 or High-Efficiency Advanced Audio Coding format. The most common use of Shoutcast is for creating or listening to Internet audio broadcasts; however, there are also video streams. The software is available to use for free or as a paid cloud service with additional professional features.

In the early days of esports for video games, Shoutcast was used by some to stream play-by-play commentary, leading to the term "shoutcaster" as a name for esports commentators.
