Torie Bosch put up an article on Slate about how when she purged a bunch of stuff back in 2021 her husband, Chris, insisted on keeping all DVDs and Blu-Ray Discs. Chris talked about what people would do if streaming went away or something disappeared from a streaming service. The idea perhaps once seemed silly, but these days with HBO MAX cutting a ton of content, shows jumping from one streamer to another, and so forth...well, maybe we should've kept all those discs.
I'll admit to having eyeballed all my DVDs and Blu-Rays in the past and unloading a chunk for a little cash or store credit at shops that bought movie and television discs. Those stores then laughed all the way to the bank as folks ran back to re-purchase those discs when their favorite show disappeared from the internet. Now, some DVD and Blu-Ray sets go for insane amounts on sites like eBay because you simply can't (legally) stream something online you used to be able to easily click on and watch. It just goes to show, always keep a saved file of something on your computer or a physical disc you own/burned. We obviously can't trust Netflix/Hulu/Disney/etc. to keep our beloved programs safe.
