Inverted Pyramid

The inverted pyramid is a metaphor used by journalists and other writers to illustrate how information should be prioritized and structured in prose (e.g., a news report). It is a common method for writing news stories and has wide adaptability to other kinds of texts, such as blogs, editorial columns and marketing factsheets. It is a way to communicate the basics about a topic in the initial sentences. The inverted pyramid is taught to mass communication and journalism students, and is systematically used in English-language media.[citation needed] The inverted or upside-down pyramid can be thought of as a triangle pointing down. The widest part at the top represents the most substantial, interesting, and important information that the writer means to convey, illustrating that this kind of material should head the article, while the tapering lower portion illustrates that other material should follow in order of diminishing importance. https://en.wikipedia.org/wiki/Inverted_pyramid_(journalism)
