Wikipedia is a free online encyclopedia that anyone can edit founded in 2001 by Jimmy Wales.

An online encyclopaedia, which crowd-sources authors to input content, edit and maintain editorial style. It is a non-profit organization based in San Francisco, California and was founded by Jimmy Wales.

Shift to online

Wikipedia effectively marked the end to the Encyclopaedia Britannica series and Microsoft's Encarta, which were CD rom based encyclopaedias, and even books on the periphery of the reference category, such as the venerable Who's Who series, mostly through attrition and as demand fell off in favour of online solutions such as Wikipedia.

Bias accusations

Wikipedia has been accused of bias over the years by companies such as the Harvard Business Review, Cracked and Gab.

Andrew Torba, CEO of Gab, has criticized Wikipedia many times both on his personal Gab account and the company's official Twitter account for their characterization of Gab as an alt-right and white supremacist populated website. They have stated that they believe their article is edited by Antifa members.

With its more than 40 million articles in 301 different languages, Wikipedia is one of the largest human collaboration efforts in history. One of the main pillars on which this wish to bring together the sum of all knowledge is based is the achievement of a neutral space. However, several studies suggest that the site suffers from a persistent gender bias as regards both content and the composition of its community. An analysis of the gender gap in the Spanish-language version of Wikipedia by an interdisciplinary team at the UOC has revealed that only 11.6% of its registered editors are women.
