News Streams are used to see the content and updates based on your preferences and get notified whenever there is an update. The News Streams can also deliver notifications for the updates on Questions, Discussions, Blog posts, Files, Documents, Polls, Tasks, Videos, Events, Ideas in the community in one place without having to query for them separately.
You can create a Custom News Stream to view the content and updates that you'd like to see and get notifications for. The notifications for these streams can be delivered through the Jive Daily app and emails, based on your choice. You can also view the stream directly by navigating to the News section of your Jive community.
Please refer to Examples of custom streams for examples and best practices for creating the streams.
