The News Content type is an example for taxonomy (or data) driven content. Taxonomy driven content is content organised by sort and filter criteria. In a Drupal context the sort and filter criteria can be either data or taxonomy based.
The Sector News content type (based on Drupal's core Article content type) is prepared for transient content that is most relevant on publication (Issue date). The Article type taxonomy allows to sort and filter News into groups for example media release or newsletter. The News archive allows the user to filter by date.
