### Founding

The foundation's creation was officially announced by Wikipedia co-founder Jimmy Wales, who was running Wikipedia within his company Bomis, on June 20, 2003.

### Operation

The foundation gets most of its funds from donations, as it is non-profit. It also looks for grants. Some companies have helped Wikimedia by giving free computer hardwares and by hosting its servers. Since people can write the wikis, Wikimedia projects are free to use. Funds are used to run computer servers and to pay staff. The Foundation had 700 employees in 2023.

## Public Opinions

The United States Congressional Oversight and Government Reform Committee opened an investigation into the operation of Wikipedia in September 2025. The initiative was initiated by two Republican representatives, who explained their actions in a letter from Congress to the Wikimedia Foundation. The commission's investigation is charged with examining "efforts by foreign entities and individuals within academic institutions funded by U.S. taxpayer dollars to influence American public opinion".
