Wikipedia

Wikipedia is a website that parodies Uncyclopedia, which parodies Decyclopedia, the website you're on right now.

History
Back in 2001, Jimbo Whales decided that people needed to edit encyclopedias, so he started Wikipedia. Then someone made a porn article, but as the admins couldn't delete articles, it stayed. Now Wikipedia has a lot of porn.

In 2010, Google started their own wiki project, but it had to get rid of Wikipedia. Thus...

Wikipedia Zero
In 2013, Wikipedia Zero was born! It was a secret project by Google to get rid of Wikipedia by blanking its pages, one page at a time. However, the content was almost always immediately restored. In 2018, the US government found out and fined Google $1,000,000,000,000,000,000,000,000,000,000,000,000. To pay off this debt, in 2020 Google announced that it would kill Classic Sites.
