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, and is one of the most popular websites by Alexa rank as of April 2019. 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.
Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger. Sanger coined its name, as a portmanteau of wiki (the Hawai’ian word for “quick”) 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 and by February 2014 it had reached 18 billion page views and nearly 500 million unique visitors per month.
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, 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. 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.
Wikipedia has been criticized for exhibiting systemic bias, for presenting a mixture of “truths, half truths, and some falsehoods”, and for being subject to manipulation and spin in controversial topics. 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.
Midland is a city in the U.S. state of Michigan in the Tri-Cities region of Central Michigan. It is the county seat of Midland County. The city’s population was 41,863 as of the 2010 census. It is the principal city of the Midland Micropolitan Statistical Area, part of the larger Saginaw-Midland-Bay City Combined Statistical Area. In 2010, Midland was named the no. 4 Best Small City to raise a family in by Forbes magazine.
By the late 1820s, Midland was established as a fur trading post of the American Fur Company supervised by the post at Saginaw. Here agents purchased furs from Ojibwe trappers. The Campau family of Detroit operated an independent trading post at this location in the late 1820s.
The Dow Chemical Company was founded in Midland in 1897, and its world headquarters are still located there. Through the influence of a Dow Chemical plant opening in Handa, Aichi, Japan, Midland and Handa have become sister cities. The Dow Corning Corporation and Chemical Bank are also headquartered in Midland.
In 1969 the city unilaterally defined a Midland Urban Growth Area (MUGA), which at the time was a territory two-miles around the city limits of Midland in an attempt to control urban sprawl.  The central policy was that as the only capable supplier of drinking water, the city would provide water services to commnities outside the MUGA such as the nearby village of Sanford, but would not provide to water services to the area within the MUGA without annexation to the city of Midland thus controlling most of the growth in the county. Since 1991 however, the policy has since been revised with a series of Urban Cooperation Act Agreements with surrounding townships which has allowed case-by-case redrawings of the MUGA line to allow Midland to sell water to the surrounding townships without annexation.
