In the past few years, the boards have created both popular threads, and also threads that have ended up being somewhat notable, for whatever reason. The plan of the archives is to store these threads permanently, however boards will only get this when there has been enough significant threads that mark keeping hold of them. Of recent, boards with threads inactive for more than 18 months have been archived, simply to help clear out stale threads, as well as threads which have reached the post limit. The archive situation has changed somewhat. More information to follow.

The Front-page Prank

In January of 2007, the front page was briefly changed to look something like a very bad web 2.0 page.

Internet Archive

Since 2005, the Internet Archive has been spidering, and collating its own archive of Channel4.

Old archive page

The old version of the sidebar from ~2006 can be seen here.
