At Mynewsdesk, we tend to think of press releases as being somewhat more formal in style than news stories. This is where we publish events and happenings that might contain company information and heavier content with more news value.
News stories are often more informal in style and written as shorter stories, updates and newsletters.
We think of blog posts as the third stage of text content, and often use them to communicate tips and tricks, or to write more personal texts to share with our customers.
