If you are an account manager of a 'parent' account that has the Broadcast feature switched on you can convert a piece of normal content (i.e. something that appears only for people that have your account open on their mobile app) to Broadcast content (i.e. it will appear in any of the accounts listed as child accounts).
This makes it easy to quickly scale content to a large number of accounts in a couple of clicks and make sure accounts in your wider network dont have to switch between accounts or locations to view the content.
