Currently, Facebook does not limit the number of viewers in any way. Therefore, you can conduct a public broadcast or one available only to selected groups of your fans.
Facebook has introduced a time limit for online broadcasts - it cannot be longer than 90 minutes.
The transmitted material remains saved as a file and is available on the timeline, or it can be deleted by the profile owner.
Prices are lower than traditional online transmission because we use Facebook's servers, which means that a significant cost is borne by the owners of FB.
