<p><b>New page</b></p><div>The '''Wayback Machine''' is the public interface of the [[Internet Archive]]'s web collections, allowing users to view historical snapshots of websites by URL and date. It has operated since the late 1990s and is among the most widely used [[Web archiving]] tools for research, journalism, legal discovery, and everyday nostalgia.<br />
<br />
==How it works==<br />
Crawlers fetch publicly reachable pages and store them (commonly in [[WARC]]-family formats). Users can browse a calendar of captures or use '''Save Page Now''' to request a fresh snapshot of a living URL. Coverage is uneven: robots exclusions, login walls, blocked bots, and JavaScript-heavy sites limit what can be stored.<br />
<br />
==Scale and milestones==<br />
In October 2025 the Internet Archive reported that the Wayback Machine had surpassed '''one trillion''' archived web pages—a civilisation-scale milestone for public web memory. Partnerships have included repairing millions of broken links on Wikipedia and End of Term crawls of U.S. government sites.<br />
<br />
==Limits==<br />
Archives are not complete mirrors of the live web; playback can omit ads, personalised content, or streaming media. Legal challenges, bandwidth costs, and site operators blocking archival bots remain ongoing risks for custodians and users.<br />
