I still have a stack of those box sets at home and honestly, it's crazy to think you could pause, rewind, watch a scene three times without depending on when France 2 decided to air it. Before you were stuck: either you recorded on VHS and it was a pain, or you missed it completely and that was that, it was gone. DVDs really democratized access to quality documentaries, so people could actually build real historical knowledge at their own pace instead of being at the mercy of the TV schedule.
Plus, those box sets usually had 3-4 episodes or more bundled together, so you had a real thematic collection at home. You could dive deep into a subject without waiting a week for the next episode. It's something we forget about when we're scrolling through 30-second documentary clips on TikTok now.
