This October, the Internet Archive will celebrate an extraordinary milestone: 1 trillion web pages preserved and available for access via the Wayback Machine.

Calendar of Events | Impact Stories | Support the Internet Archive | Press Kit

Since 1996, the Internet Archive has worked with libraries and partners around the world to build a shared digital library of humanity’s online history: capturing websites large and small—from breaking news to forgotten personal pages—so they remain accessible for future generations.

The series of events scheduled throughout October will highlight the memories, makers, and movements that have made this achievement possible, and will look ahead to the future of web preservation as we continue building the web’s collective memory together.

This October, the Internet Archive’s Wayback Machine is projected to hit a once-in-a-generation milestone: 1 trillion web pages archived. That’s one trillion memories, moments, and movements—preserved for the public and available to access via the Wayback Machine.

We’ll be commemorating this historic achievement on October 22, 2025, with a global event: a party at our San Francisco headquarters and a livestream for friends and supporters around the world. More than a celebration, it’s a tribute to what we’ve built together: a free and open digital library of the web.

Join us in marking this incredible milestone. Together, we’ve built the largest archive of web history ever assembled. Let’s celebrate this achievement—in San Francisco and around the world—on October 22.

October 27—Wayback to the Future: Celebrating the Open Web

5:00-8:00pm PT
Riggs Library, Georgetown University
Healy Hall, Library Walk, Washington, DC 20057
Register now for IN-PERSON tickets

​Join the Foundation for American Innovation, the Massive Data Institute and the Internet Archive at Georgetown University’s historic Riggs Library for Wayback to the Future: Celebrating the Open Web—Past, Present, and Possible.

​The open web was once defined by experimentation, decentralization, and possibility. The technological advancements were driven by the desire for a place where new voices and ideas could flourish. Today, consolidation and walled gardens challenge that vision. Together, we’ll look back at the internet’s origins to spark a forward-looking conversation about how to keep the web free, open, and innovative.

Speakers include:

​Moderator: Luke Hogg — Director of Technology Policy, FAI
Brewster Kahle — Founder & Director, Internet Archive
Vint Cerf — Chief Internet Evangelist, Google
Cindy Cohn — Executive Director, Electronic Frontier Foundation
Jon Stokes – Co-founder, Ars Technica
