Wikipedia – The Free Encyclopedia – is "the free wiki encyclopedia that anyone can edit". Brainchild of Jimmy Wales (and others); and the original project of the subsequent Wikimedia Foundation (WMF), Wikipedia strives claims to have an officially 'neutral point of view' (NPOV); but is often accused by people on each side of the political or other spectrums of being biased towards the other side. Wikipedia is the biggest fish in the global wiki pond, and receives far more traffic, and editing activity, than any other wiki. However, despite Wikipedias' claim to being an 'encyclopedia'; many academic institutes and other professional organisations recommend that Wikipedia is not used as a primary source of information, due to the fact that many articles are frequently incorrect, and many articles have a seemingly extremely low threshold of 'reliable source' references and citations! Indeed, many Wikipedia articles fail their own verifiability criteria, and can remain for many years without any citations, dispite warning banners highlighting the lack of said citations (and threatening to delete said unreferenced articles), and this even includes biographical articles for living people . . . and the English Wikipedia allows articles to be 'promoted' to a good article (GA) status despite failing their own criteria on having adequate reliable source citations, editorial conjecture, and even original research!

Historically, when Wikipedia was founded, it released all textual wiki content under the GNU Free Documentation License (GFDL). However, during 2009, existing Wikipedia wikis migrated to a new license – the Creative Commons Attribution-Share Alike 3.0 unported license (CC-BY-SA 3.0); and all content published until that migration date could be retro-released under either or both licenses. All content published after the migration date is released under only the CC-BY-SA 3.0 license, as are any newly created Wikipedia language versions. [2]
