The Internet Archive, which he founded in 1996, now preserves 90+ petabytes of data - the books, Web pages, music, television, and software that form our cultural heritage, working with more than 1000 library and university partners to create a digital library, accessible to all.

He first called builders to "Lock the Web Open" using decentralized technologies in 2015, and continues to write about, experiment, cajole, and cheer on those creating decentralized systems we can trust.
