A newspaper is a serial publication containing news about current events, other informative articles (listed below) about politics, sports, arts, and so on, and advertising. A newspaper is usually, but not exclusively, printed on relatively inexpensive, low-grade paper such as newsprint. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. As of 2017, most newspapers are now published online as well as in print. The online versions are called online newspapers or news websites. Newspapers are typically published daily or weekly. News magazines are also weekly, but they have a magazine format. General-interest newspapers typically publish news articles and feature articles on national and international news as well as local news. The news includes political events and personalities, business and finance, crime, weather, and natural disasters; health and medicine, science, and computers and technology; sports; and entertainment, society, food and cooking, clothing and home fashion, and the arts.
