Many universities have content available online, some as unlisted videos (you need the link) and some totally public. For example, I recently came across the uclaphysicsvideo channel. 90 short videos containing experiments, most of them are 10 years old and have very few views (except for a few that have gone viral and have lots of views). I often feel the need to archive these channels, but I don't have the resources to do so. I fear that many of these channels will eventually disappear in the coming years, which would result in the loss of valuable information.
