It hasn't been without controversy.

Hoaxes, edit wars and debates over accuracy have all been part of its journey.

A page dedicated to a completely made-up god called Jarido Wenz stayed online for nearly 10 years before being caught.

Britney Spears, Donald Trump and Jesus are among the most edited individuals, racking up tens of thousands of amendments over the years.

Stricter sourcing rules and a global community of volunteer editors try and keep misinformation in check.

Those volunteers are key.

Let's crunch some numbers.

Wikipedia is edited by nearly 250,000 volunteers every month, with edits made 350 times every minute.

The most edited page is a list of WWE personnel, yes, the wrestling brand, with more than 59,000 changes so far.

At 25, it faces new challenges, disinformation, deepfakes and artificial intelligence.

Wikipedia is the only website in the top 10 most visited global sites run by a non-profit.

And yes, people do use that familiar pop-up banner to make donations.

Wikipedia's mission remains the same.

Free knowledge for all.
