The following applies to the Topics and regions that you set
– as a default in Newsroom settings (in the menu under the gearwheel).
– 
in the distribution settings for any material in Publish.

After adding one or more topics and subtopics, the material (e.g. press release) will at publication be sent to journalists that are following any of these.
By adding one or more regions, you will in addition also reach journalists that are following any of those provinces and/or districts. Even though they are not necessarily following any of your topics or subtopics.

Adding regional distribution is a good way to reach local journalists, who might not so much be focused on certain topics, but are keen to find out about everything that relates to their province or district.
