Wikipedia was first founded on January 15, 2001. Today, it turns 25!

Wikipedia is written, edited, and fact checked by nearly 250,000 people, all volunteers from around the world. This meaningful work continues to ensure that Wikipedia is reliable, well sourced, and from a neutral point of view.

At this occasion, the Wikimedia Foundation launched an immersive journey to show how Wikipedia came to be and why it is still a testament to collaboration and consensus. You can also take a quiz to find out “Which Wikipedia of the Future are you?”!
