Wikipedia celebrates 15 years of free knowledge

Community celebrates Wikipedia and sister projects with nearly 150 events on six continents

Wikimedia Foundation announces endowment to sustain Wikipedia for the future

San Francisco, CA. January 14, 2016 -- This Friday marks the 15th anniversary of Wikipedia, the world’s free encyclopedia that anyone can edit. This week, we celebrate not just Wikipedia, but the birth of an idea: that anyone can contribute to the world’s knowledge. Globally, readers and editors are coming together to celebrate, with nearly 150 events across six continents. From editing marathons in Bangladesh and lectures in Switzerland, to picnics in South Africa and a conference in Mexico, the world is celebrating the joy of knowledge.

As part of this milestone, the Wikimedia Foundation is pleased to announce the Wikimedia Endowment, a permanent source of funding to ensure Wikipedia thrives for generations to come. The Wikimedia Endowment will empower people around the world to create and contribute free knowledge, and share that knowledge with every single human being. Our goal is to raise $100 million over the next 10 years. The Endowment has been established, with an initial contribution by the Wikimedia Foundation, as a Collective Action Fund at the Tides Foundation.

Wikipedia launched on January 15, 2001 with a bold vision: a world in which every single human being can freely share in the sum of all knowledge. At the time, the idea that people around the world would collaborate to build an encyclopedia—for free—seemed unbelievable. Since then, Wikipedia has grown to more than 36 million articles in hundreds of languages, used by hundreds of millions of people all over the world. Wikipedia and its sister projects are still built by volunteers around the world: each month, roughly 80,000 volunteer editors contribute to Wikimedia sites.

"Wikipedia challenged us to rethink how knowledge can be gathered and shared." said Wikipedia founder Jimmy Wales, "Knowledge is no longer handed down from on high, instead it is freely shared by everyone online. Wikipedia seemed like an impossible idea at the time—an online encyclopaedia that everyone can edit. However, it has surpassed everyone's expectations over the past 15 years, thanks to the hundreds of thousands of volunteers around the world who have made Wikipedia possible."

We're celebrating Wikipedia's global community with a commemorative website and week-long campaign, collecting and sharing the stories of individuals and organizations that have helped develop Wikipedia into the world's largest collection of collaboratively created free knowledge. These stories show the truly global nature of the Wikimedia community: from Ziyad Alsufyani, a medical student at Taif University in Ta’if, Saudi Arabia who has been editing the Arabic Wikipedia since 2009, to Susanna Mkrtchyan, a professor and devoted grandmother working to give Armenian students better educational opportunities. We will continue to collect stories throughout the month of January.

Today, we celebrate all of the projects, partnerships, events, and joy the Wikimedia movement has inspired over the past 15 years, with many still to come. Wikipedia is much more than a website. Wikipedia and its sister Wikimedia projects represent a global, ever-expanding resource and community for free knowledge. Here are just a few examples:

  • Wikipedia started in January 2001 in English, but soon expanded to other languages—within the first year, it grew to 18 languages. Today, it is available in nearly 300.
  • Volunteers constantly edit and improve Wikipedia. Every hour, roughly 15,000 edits are made to Wikipedia. Every day, around 7,000 new articles are created.
  • Wikipedia became one of the top 10 websites in the world in 2007, and the only non-profit website anywhere near the top.
  • It’s not just Wikipedia. There are 11 other Wikimedia free knowledge projects, including Wikimedia Commons, with more than 30 million freely licensed images, as well as Wiktionary, Wikisource, Wikivoyage, and more.
  • The Wikimedia community supports global projects that spread the joy of knowledge. Wiki Loves Monuments, a global photo competition, launched in 2010 to document images of cultural heritage. In 2011, the contest was named the largest photo competition in the world. Companion projects like Wiki Loves Earth, Wiki Loves Africa, and even Wiki Loves Cheese document other knowledge from around the globe.
  • Volunteers around the world have built hundreds of partnerships with galleries, libraries, museums to make institutional collections more broadly available. These partnerships have contributed to more than 1.5 million images of cultural works on the Wikimedia projects.

About Wikipedia

Wikipedia is the world’s free knowledge resource. It is a collaborative creation that has been added to and edited by millions of people from around the globe since it was created in 2001: anyone can edit it, at any time. Wikipedia is offered in hundreds of languages containing a total of more than 36 million articles, and visited by nearly half a billion people every month. Wikimedia and its sister projects are the largest collection of free knowledge in human history.

About the Wikimedia Foundation

The Wikimedia Foundation is the non-profit organization that supports and operates Wikipedia and its sister projects. Wikipedia attracts more than 15 billion page views each month. Every month roughly 80,000 people edit Wikipedia and its sister projects, collectively creating, improving, and maintaining its more than 35 million articles across hundreds of languages -- this all makes Wikipedia one of the most popular web properties in the world. Based in San Francisco, California, the Wikimedia Foundation is a 501(c)(3) charity that is funded primarily through donations and grants.

About the Wikimedia Endowment

The purpose of the Wikimedia Endowment is to serve as a perpetual source of support for the operation and activities of Wikipedia and its sister projects. It will empower people around the world to create and contribute free knowledge, and share that knowledge with every single human being. The Endowment has been established, with an initial contribution by Wikimedia Foundation, as a Collective Action Fund at Tides Foundation. Tides is a public charity with a 40-year track record of holding and managing charitable funds for nonprofit organizations. An Advisory Board, nominated by the Wikimedia Foundation and appointed by Tides, will make recommendations to Tides related to the Endowment. Tides or the Wikimedia Foundation may choose to transfer the Endowment from Tides to the Wikimedia Foundation, or other charities identified by the Wikimedia Foundation. At that point, the Endowment would continue to be a permanent, income-generating fund to support the Wikimedia projects.
