 Together, we are creating the most comprehensive encyclopedia that has ever existed, Wikipedia. It's also free, free to read, free to edit, free to share. It is available in more than 200 languages and it's accessible to anyone with access to the internet or mobile phone. Roughly six out of every seven people today have mobile access. Mobile technology is the future of knowledge sharing. It has the potential to bring Wikipedia to billions of people. However, despite Wikipedia's free content, most people simply can't afford the data charges to access Wikipedia. That's why the non-profit that supports Wikipedia runs a program called Wikipedia Zero, which works with mobile carriers to waive the data charges for accessing Wikipedia. Removing the costs of accessing Wikipedia may sound trivial, but it's one small change that makes a huge difference. Students will do their homework and research careers. Doctors will study treatments. Small businesses will find knowledge to innovate. People will better understand their own history, society and culture. We invite mobile operators all over the world to make knowledge truly free. Wikipedia belongs to all of us. Imagine a world in which every single person on the planet has equal access to the sum of all human knowledge.
