Wikimedia Foundation

Nonprofit operator of Wikipedia

Overview

The Wikimedia Foundation runs Wikipedia and the family of Wikimedia free-knowledge projects as a nonprofit organization. It supports reading, contributing, and sharing content through software experiences and community programs, funded by donations from individuals and institutional grants. Its products work by letting volunteers write and edit articles, and readers access them for free through web and mobile experiences that prioritize openness and collaboration. Unlike for-profit tech platforms, Wikimedia focuses on free knowledge for everyone and backs the volunteer communities who create it, along with advocacy for policies that enable free knowledge to thrive. Its goal is a world in which every person can freely share in the sum of all knowledge.

Debunking myths and more: New "A Wiki Minute" videos added to the series.

Debunking myths and more: New "A Wiki Minute" videos added to the series. 14 July 2026 by Marina Ramos-Smith, Brand Studio, Wikimedia Foundation Raise your hand if you've ever had to explain to your teacher why you should be able to use Wikipedia in school. Or if you've recently encountered people who think they don't need Wikipedia because AI can "answer" every single one of their questions. If that's your case, then these new "A Wiki Minute" videos were made for you. With this latest set of animations, Wikimedia Foundation, Inc. answer some of the most common questions Wikimedia Foundation, Inc. has been asked, as well as tackling some of the biggest misconceptions about how Wikipedia works - and Wikimedia Foundation, Inc. is doing it in only a minute. Check out the new videos below: In addition to these questions, Wikimedia Foundation, Inc. also released three videos back in 2025 that focused on the role of Wikipedia with the advent of AI, what it takes to run a platform like Wikipedia, and why you can trust information that's written and edited by volunteers. Make sure to check those out if you haven't already. The Wikimedia Foundation uses these videos to help communicate complex ideas in a quick and effective manner. Wikimedia Foundation, Inc. share them with the press and donors, with followers on social media, and with different audiences when Wikimedia Foundation, Inc. create new marketing campaigns. Available in English with subtitles (.SRT) in Arabic, French, German, Portuguese (BR), and Spanish (MX), the videos can be found on Wikimedia Commons and are ready to use. Wikimedia Foundation, Inc. has made it easier for you to create localized versions of A Wiki Minute videos and incorporate them into your work: You'll find a version of each of the 19 videos - including the three new ones - without voiceover recording on Wikimedia Commons, so you can recreate them in your own language. AI, political agendas, and trust: Deciding on which topics to explain. In thinking of the topics Wikimedia Foundation, Inc. could cover in only a minute, Wikimedia Foundation, Inc. always consider the questions Wikimedia Foundation, Inc. has seen the most demand for answers first. Then, Wikimedia Foundation, Inc. ponder which of those can be successfully explained in a quick and straightforward manner. Wikimedia Foundation, Inc. balance what will remain true for the longest time (Wikimedia Foundation, Inc. call it "evergreen" content) with what Wikimedia Foundation, Inc. see as the most pressing need for explaining. That's how Wikimedia Foundation, Inc. land on the topics for all Wiki Minute videos. About "A Wiki Minute" videos. 5 years ago, the Wikimedia Foundation's Communications department set off to create a series of videos that helped its organization, Movement's affiliates, and Wikimedia enthusiasts all over the world better explain how the Wikimedia universe works. Since then, Wikimedia Foundation, Inc. has created 19 videos that have been translated into multiple languages. These videos have been proven to build understanding and even affinity for Wikimedia and its projects, as described in its first Diff post about the series. Check out the project's Meta-Wiki page to watch all the available videos. Can you help Wikimedia Foundation, Inc. translate this article?

Wikipedia editors plan strike over Wikimedia's decision to disband Community Tech team

The Wikimedia Foundation has sparked backlash from Wikipedia editors after disbanding its six-person Community Tech team, which handled editor-requested bug fixes, moderation tools and workflow improvements through the Community Wishlist process. Editors are debating protest actions including editing strikes, pausing vandalism cleanup and replacing fundraising banners with messages criticising the layoffs. The foundation, which reported nearly $300 million in assets in its latest annual report, said the restructuring followed months of internal reviews and that community requests will now be handled across the wider Product and Technology department. The situation has intensified amid allegations of union busting, as several affected employees were involved in early unionisation efforts with Wiki Workers United. The foundation denies any connection between the restructuring and union activities.

The top 10 photos from the Wiki Loves Monuments photo contest will inspire wanderlust.

The top 10 photos from the Wiki Loves Monuments photo contest will inspire wanderlust. Apr 30, 2026 The Wikimedia Foundation has announced the winners of the 16th edition of the Wiki Loves Monuments photo competition - with three of the top five entries hailing from Iran. Each year since 2010, photographers from around the globe have come together to celebrate cultural heritage through their camera lens. Since it's Wikimedia, each photo is uploaded under a Creative Commons license, so it's free to be used by other people. For the most recent edition of the contest, 3,789 people submitted 227,918 photos to locally run national contests in September and October 2025. Each country then submitted its winners to a nine-person expert jury, who closely examined and identified the below 25 winners during a multi-month selection process. This year's winner captured a wall and gate near the Dayr-e Gachin Caravanserai in Iran. The Wikimedia Foundation says that Dayr-e Gachin has been called the "mother of Iranian caravanserais" due to its size and importance. "Over all its years, Wiki Loves Monuments photographers have collectively donated millions of images to Wikimedia Commons, a freely licensed media repository that supports Wikipedia and other websites," says the Wikimedia Foundation. "Each photo adds another nugget of knowledge to the world's collection." PetaPixel articles may include affiliate links; if you buy something through such a link, PetaPixel may earn a commission.
