The Pyramid Structure

All of us have been reading newspapers for many many years. Just in case you have not noticed the following about news stories;

This structure is most commonly used in the newspaper industry. Here, at the beginning of an article, the whole story is told in one bold paragraph, in a few short statements at the beginning (the apex of the pyramid). The next paragraph tells the same story with more detail, and the third paragraph the same story with even more and longer detail. This technique allows the editor to cut the article to fit the space available from the bottom of the pyramid of copy.

This can be useful for presentations because it allows you to take a similar editing approach from the bottom up.
