Wikipedia:25th anniversary

A quarter century of free knowledge

On 15 January 2026, Wikipedia celebrated the 25th anniversary of its founding in 2001. The English edition has grown to include more than 7 million articles—all written collaboratively by volunteers.

Wikipedia started as an ambitious idea to create a free encyclopedia, written by volunteers, for everyone in the world. It seemed impossible. Over 25 years, Wikipedia has become the largest collection of open knowledge in history. How did it happen? (1 min 30 s)

Have a nice 25th one!!

Congratulations -> to the structured knowledge framework!
