The free online encyclopedia Wikipedia has been criticized since its creation in 2001. Most of the criticism has been directed toward its content, community of established volunteer users, process, and rules. Critics have questioned its factual reliability, the readability and organization of its articles, the lack of methodical fact-checking, and its political bias.
The reliability of Wikipedia and its user-generated editing model, particularly its English-language edition, has been questioned and tested. Wikipedia is written and edited by volunteer editors, who generate online content with the editorial oversight of other volunteer editors via community-generated policies and guidelines. The reliability of the project has been tested statistically through comparative review, analysis of the historical patterns, and strengths and weaknesses inherent in its editing process. The online encyclopedia has been criticized for its factual unreliability, principally regarding its content, presentation, and editorial processes. Studies and surveys attempting to gauge the reliability of Wikipedia have mixed results. Wikipedia's reliability was frequently criticized in the 2000s but has been improved; its English-language edition has been generally praised in the late 2010s and early 2020s.

On Wikimedia Foundation projects, an arbitration committee (ArbCom) is a binding dispute resolution panel of editors. Each of Wikimedia's projects are editorially autonomous and independent, and some of them have established their own arbitration committees who work according to rules developed by the project's editors and are usually annually elected by their communities. The arbitration committees generally address misconduct by administrators and editors with access to advanced tools, and a range of "real-world" issues related to harmful conduct that can arise in the context of Wikimedia projects. Rulings, policies and procedures differ between projects depending on local and cultural contexts. According to the Wikimedia Terms of Use, users are not obliged to have a dispute solved by an arbitration committee.
The Colbert Report, which premiered in American cable television on October 17, 2005, has had a massive cultural impact since its inception. Issues in and references to American and world culture are attributed to the character played by Stephen Colbert, who calls his followers the Colbert Nation. The Colbert Report is a late-night talk and satirical news program hosted by Colbert that aired on Comedy Central from October 17, 2005, to December 18, 2014, for 1,447 episodes. The show focused on a fictional anchorman character named Stephen Colbert, played by his real-life namesake. The character, described by Colbert as a "well-intentioned, poorly informed, high-status idiot," is a caricature of televised political pundits. The show satirized conservative personality-driven political talk programs, particularly Fox News' The O'Reilly Factor. The Colbert Report is a spin-off of Comedy Central's The Daily Show, where Colbert was a correspondent from 1997 to 2005.
