We owe you an explanation.

July 16: An important update for readers in the United States.

You deserve an explanation, so please don't skip this 1-minute read. It's Thursday, July 16, and you only had a small chance of seeing our message. This year, Wikipedia has seen fewer visitors and fewer new supporters, so your visit today means a lot. We hope that Wikipedia has given you at least $2.75 of knowledge recently. If everyone who finds Wikipedia useful gave $2.75, we'd hit our goal in a few hours.

It's been 25 years and Wikipedia is still free. It's still created by people, not machines, and we don't run ads or put up paywalls because we're not here to make a profit off your attention. In other words, it's still the internet we were promised.

Less than 2% of our readers donate, so if you've never given and Wikipedia has provided you with at least $2.75 worth of knowledge, donate today. If you are undecided, remember any contribution helps.

Thank you for joining the 2% of readers who give.

25 years ago Wikipedia was a dream. A dream built piece by piece by people, not machines. Now, with 65 million articles and 260,000 global volunteers, Wikipedia is a place of free, collaborative, and accessible knowledge—run by a nonprofit, not a corporation or billionaire. Your donation isn't just supporting a website; it's investing in the world's largest collaborative project of human intelligence—written by humans, for humans. Please join the small percentage of readers who give what they can to help keep Wikipedia strong and growing. Thank you.
