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.
Laredo (// lə-ray-doh; Spanish: [laˈɾeðo]) is the county seat of Webb County, Texas, United States, located on the north bank of the Rio Grande in South Texas, across from Nuevo Laredo, Tamaulipas, Mexico. According to the 2010 census, the city population was 236,091, making it the tenth-most populous city in the state of Texas and third-most populated on the Mexico–United States border, after San Diego, California, and El Paso, Texas. Its metropolitan area is the 178th-largest in the U.S. and includes all of Webb County, with a population of 250,304. Laredo is also part of the cross-border Laredo-Nuevo Laredo Metropolitan Area with an estimated population of 636,516.
Because Laredo is 95.6 percent Hispanic and Latino, it is one of the least ethnically diverse cities in the United States. When economic diversity, household diversity and social class diversity, are considered, Laredo is rated the 19th least diverse city overall out of the 313 largest cities in the nation.
Laredo’s economy is based on international trade with Mexico. Most major transportation companies have a facility in Laredo. The city’s location on the southern end of I-35 close to the manufacturers in northern Mexico promotes its vital role in trade between the two nations. Laredo International Airport is within the Laredo city limits, while the Quetzalcoatl International Airport is nearby in Nuevo Laredo on the Mexican side.
