Posted by YouTube live streams are generally pretty good, but getting noticed in the live comment stream is tricky, especially when there are thousands or even hundreds of thousands watching or commenting.
To combat this, YouTube has introduced Super Chat, a way for commenters to get more noticed by their favorite content creators by paying to pin comments to the top.
The way Super Chat works is by allowing individual users to pay to promote their comment for a temporary period of time (up to 5 hours).
The comment is highlighted and pinned to the top of the comments, and the creator who is hosting the live stream can reply. To send a Super Chat, send a dollar sign in the live chat, then select ‘Send a Super Chat’.
