Wikipedia

 is a multi-language, open-content online encyclopedia operated by the Wikimedia Foundation. Originally conceived as a way to distribute multimedia educational materials to developing countries, it has ballooned into one of the ten highest-traffic websites in the world, with a in the top 3 for virtually any covered topic. Nearly anyone with an internet connection can participate; the size and diversity of the resulting editor base mean that social and political activities are far more important than content. As journalistic and academic attention grew, Wikipedia's infrastructure began to influence real-world concepts of scholarship, governance, and marketing.

Doom-related history
In the early days of the Doom Wiki, Wikipedia had a fair amount of related coverage, and several articles were used as bases for in-depth writeups here. Because the two share a wiki engine, MediaWiki, "back office" components such as templates and help pages could often be imported as well. The nascent community, infused with (thousands of articles documented, , and ), welcomed Doom content and encouraged power users to contribute to both sites. In a few cases, Wikipedia even disseminated news about fan projects.

Since that time, Wikipedia has increasingly excluded video game content (and pop culture without representative celebrities, in general). Far stricter thresholds for crossover media coverage were imposed, and articles about minor public personages removed by corporate decree, under new, unilaterally established rules regarding editorial neutrality, notability (defined as references to a work in secondary, mainstream media sources), or personal privacy protection. By the letter of policy, many more Doom topics could in fact have articles if someone thoroughly scoured offline sources from the 1990s, such as magazines, newspapers, and trade journals. In practice, Doomers not only considered this onerous but were reluctant to clash with Wikipedia's voting bloc, who typically stonewall topics associated with teenagers unless by mainstream news reporting. For example, has a Wikipedia article because it received a modern online-heavy PR campaign with regular social media updates. DEU, far more important to the overall narrative of Doom's impact, does not. The overall effect was to drive editors of Doom content toward the Doom Wiki (at that time hosted on Wikicities), where such material could be considered as on-topic or not in accordance with rules established to properly serve the needs of the same community creating the material.

Consequently, as of 2018, Wikipedia has very limited relevance to the Doom Wiki. It occasionally provides bibliographic guidance, and indirectly funds MediaWiki's software development, which continues to support an ecosystem of third-party database maintainers such as MancuNET. Wiki editors engaged in content research, however, are much better off simply doing their own play testing, or consulting with fellow Doomers on esoteric or historical subjects.
