A newspaper is a serial publication containing news, other informative articles, and advertising. A newspaper is usually but not exclusively printed on relatively inexpensive, low-grade paper such as newsprint. The news organizations that publish newspapers are themselves often metonymically called newspapers. Most newspapers are now published online as well as in print. The online versions are called online newspapers or news sites. General-interest newspapers typically publish news articles and feature articles on national and international news as well as local news.
