Wikipedia
Wikipedia (/ˌwɪkɪˈpiːdiə/ (
listen), /ˌwɪkiˈpiːdiə/ (listen) WIK-ih-PEE-dee-ə) is a multilingual online encyclopedia with exclusively free content and no ads (though donations are accepted), based on open collaboration through a model of content editing using web-based applications such as web browsers, called wiki. It is the largest and most popular general reference work on the World Wide Web,[3][4][5] and is one of the most popular websites by Alexa rank as of April 2019.[6] It is owned and supported by the Wikimedia Foundation, a non-profit organization that operates on money it receives from donors to remain ad-free.[7][8][9][10]
Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger.[11] Sanger coined its name,[12][13] as a portmanteau of wiki (the Hawai’ian word for “quick”[14]) and “encyclopedia“. Initially an English-language encyclopedia, versions in other languages were quickly developed. With 5,861,248 articles,[notes 3] the English Wikipedia is the largest of the more than 290 Wikipedia encyclopedias. Overall, Wikipedia comprises more than 40 million articles in 301 different languages[15] and by February 2014 it had reached 18 billion page views and nearly 500 million unique visitors per month.[16]
In 2005, Nature published a peer review comparing 42 hard science articles from Encyclopædia Britannica and Wikipedia and found that Wikipedia’s level of accuracy approached that of Britannica,[17] although critics suggested that it might not have fared so well in a similar study of a random sampling of all articles or one focused on social science or contentious social issues.[18][19] The following year, Time magazine stated that the open-door policy of allowing anyone to edit had made Wikipedia the biggest and possibly the best encyclopedia in the world, and was a testament to the vision of Jimmy Wales.[20]
Wikipedia has been criticized for exhibiting systemic bias, for presenting a mixture of “truths, half truths, and some falsehoods”,[21] and for being subject to manipulation and spin in controversial topics.[22] But by 2017, Facebook announced that it would help readers detect fake news by suggesting links to related Wikipedia articles. YouTube announced a similar plan in 2018.[23]
Niagara Falls
Niagara Falls (/naɪˈæɡrə/ ny-ag-ra) is a city in Niagara County, New York, United States. As of the 2010 census, the city had a total population of 50,193, down from the 55,593 recorded in the 2000 census. It is adjacent to the Niagara River, across from the city of Niagara Falls, Ontario, and named after the famed Niagara Falls which they share. The city is within the Buffalo–Niagara Falls Metropolitan Statistical Area as well as the Western New York region.
While the city was formerly occupied by Native Americans, Europeans who migrated to the Niagara Falls in the mid-17th century began to open businesses and develop infrastructure. Later in the 18th and 19th centuries, scientists and businessmen began harnessing the power of the Niagara River for electricity and the city began to attract manufacturers and other businesses that were drawn by the promise of inexpensive hydroelectric power. After the 1960s, however, the city and region witnessed an economic decline following an attempt at urban renewal under then Mayor Lackey, consistent with the rest of the Rust Belt as industries left the city old line affluent families relocated to nearby suburbs and out of town.
Despite the decline in heavy industry, Niagara Falls State Park and the downtown area closest to the falls continue to thrive as a result of tourism. The population, however, has continued to decline from a peak of 102,394 in the 1960s due to the loss of manufacturing jobs in the area.
