What it’s all about
Every October 27, the world takes a moment to notice something we usually take for granted: the recordings that hold our shared memory. Films, radio broadcasts, television programs, and sound recordings are among the most powerful ways a culture remembers itself, and also among the most fragile. UNESCO established the World Day for Audiovisual Heritage to draw attention to how easily this material can vanish, and to celebrate the archivists, librarians, and technicians who work to keep it alive. The date marks the anniversary of the 1980 adoption of a UNESCO recommendation on safeguarding moving images.
The threat is real and quiet. Magnetic tape breaks down chemically. Film stock warps, fades, and in older cases was made of unstable, flammable material. Just as damaging, the machines needed to play these formats are disappearing, so a perfectly good tape becomes unreadable simply because nothing can spin it anymore. A recording nobody can play is, for practical purposes, already lost.
A little fragile history
Much of the twentieth century was captured on media never designed to last. Early film was often discarded after its commercial run, and a great deal of the silent era is simply gone. Radio and television were frequently broadcast live and never recorded, or taped over to save money on expensive stock. What survives often does so by luck. That is exactly why deliberate preservation matters so much: heritage is not automatically kept, it is chosen and maintained by people who decide it is worth the effort.
The moment a format’s last working playback machine dies, everything recorded on it goes silent.
How to make the most of it
You do not need to run a national archive to take part. The same principles the professionals use scale down to your own shelf of home movies and voicemails. Start by finding the oldest, most vulnerable recordings you own and getting them into digital form, because those are the ones on the clock. Then protect what you make: keep multiple copies, in more than one place, and check on them from time to time so a dead drive does not surprise you years later.
Beyond your own collection, October 27 is a fine excuse to appreciate what has been saved. Visit a free public archive, watch a piece of footage from before you were born, or support a local library or film society doing preservation work. Ask older relatives to help you name the faces in an old clip while they still can. The heritage worth keeping is not only in famous vaults. A lot of it lives in ordinary homes, waiting for someone to press record on the future.
How to celebrate
- 1Digitize a home movie
Dig out those VHS tapes, camcorder cassettes, or 8mm reels in the closet. Magnetic tape degrades and old formats become unplayable as machines disappear, so time matters. Use a USB video-capture device with an old VCR, or take reels to a local transfer service. Save the files in a lossless or high-bitrate format, not a heavily compressed one.
- 2Back up in three places
Archivists follow the 3-2-1 rule: three copies of anything you care about, on two different types of media, with one copy kept off-site. For family videos and photos, that might mean your computer, an external drive, and a cloud account. Check the drives once a year, because storage silently fails when left untouched.
- 3Label and date everything
An unlabeled file is half-lost. Rename digitized clips with the year, event, and who is in them while you still remember, for example 1994-Grandpa-birthday. Add the same details in the file description or a simple text log. Future-you, or your kids, will be able to actually find and understand what you saved.
- 4Explore a public archive
Spend an evening in a free, legal archive of the world's audiovisual past. Try the Internet Archive's moving-image collection, the Library of Congress National Screening Room, or the British Film Institute's online player. Watch a newsreel, a silent short, or an old public-information film, and notice how much would be gone if no one had saved it.
