Well-known newspapers include ''The Wall Street Journal'', ''The New York Times'', and ''USA Today''. Although the cost of publishing has increased over the years, the price of newspapers has generally remained low, forcing newspapers to rely more on advertising revenue and on articles provided by a major wire service, such as the Associated Press or Reuters, for their national and world coverage. With very few exceptions, all the newspapers in the U.S. are privately owned, either by large chains such as Gannett or McClatchy, which own dozens or even hundreds of newspapers; by small chains that own a handful of papers; or in a situation that is increasingly rare, by individuals or families. Major cities often have "alternative weeklies" to complement the mainstream daily papers, such as New York City's ''The Village Voice'' or Los Angeles' ''LA Weekly''. Major cities may also support a local business journal, trade papers relating to local industries, and papers for local ethnic and social groups. The five most popular websites used in the U.S. are Google, YouTube, Amazon, Yahoo, and Facebook.
