Jimmy Wales, co-founder of Wikipedia, dreamt about a world in which every single person on the planet is given free access to the sum of all human knowledge. In 2001, he founded Wikipedia, making that dream a reality. Today, Wikipedia is the seventh most visited website in the world. There are 500 million unique visitors every month visiting the site from every country in the world. Wikipedia contains nearly 5 million articles, that is being added to at the rate of 750 articles every day.
Wikipedia is a free encyclopedia that is written by thousands of volunteers, and has content in 288 languages. Key statistics for the site are: 8 languages that have over 1,000,000 entries; 46 languages have at least 100,000 entries; 120 languages have at least 10,000 entries and 223 languages have at least 1,000 entries. For Wikipedia, “free” means not just only no cost for the readers or contributors, but also freedom of speech. Everyone can copy, modify, and redistribute the content, both commercially and for private use.
In 2004 Jimmy Wales and Angela Beesley Starling announced the creation of their next project named Wikia. Wikia follows the same success model of Wikipedia. Wikia is a free web hosting service for wikis. The site is free of charge and derives its income from advertising. It publishes all user-provided text under copyleft licenses (https://copyleft.org/) . Today Wikia has more than 136 million readers every month and is written in 200 language.
Jimmy Wales dream about “the sum” of all human knowledge came true twice, due to his perseverance and his decision on sharing the vision of his dream with others.
