The headline is the text at the top of a newspaper article, indicating the nature of the article below it.

It is sometimes termed a news hed, a deliberate misspelling that dates from production flow during hot type days, to notify the composing room that a written note from an editor concerned a headline and should not be set in type.

A headline's purpose is to quickly and briefly draw attention to the story. It is generally written by a copy editor, but may also be written by the writer, the page layout designer, or other editors. The most important story on the front page above the fold may have a larger headline if the story is unusually important. The New York Times's 21 July 1969 front page stated, for example, that "MEN WALK ON MOON", with the four words in gigantic size spread from the left to right edges of the page.

The film The Shipping News has an illustrative exchange between the protagonist, who is learning how to write for a local newspaper, and his publisher:

In the United States, headline contests are sponsored by the American Copy Editors Society, the National Federation of Press Women, and many state press associations.

World is a common name for the whole of human civilization, specifically human experience, history, or the human condition in general, worldwide, i.e. anywhere on Earth.

In a philosophical context it may refer to: (1) the whole of the physical Universe, or (2) an ontological world (see world disclosure). In a theological context, world usually refers to the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred. The "end of the world" refers to scenarios of the final end of human history, often in religious contexts.

World history is commonly understood as spanning the major geopolitical developments of about five millennia, from the first civilizations to the present.

World population is the sum of all human populations at any time; similarly, world economy is the sum of the economies of all societies (all countries), especially in the context of globalization. Terms like world championship, gross world product, world flags etc. also imply the sum or combination of all current-day sovereign states.
