What is the advantage of inverted triangle style of reporting?

The ‘inverted triangle’ is a format used when reporting hard news for a newspaper.

The advantage of this style is that the most important portions of the report appear in the lead sentence and in the lead paragraph. The following paragraphs contain details of lesser importance.

A reader in a hurry can get the gist of the report by scanning the lead paragraph.

Since newspapers are often pressed for space, the story in ‘inverted pyramid’ style can be trimmed from the bottom without losing its essence.
