Setting the scene
MPEG-2 compression and dual-layer manufacturing pushed factories to retool from CD lines while rental chains like Blockbuster hedged formats.
What happened
CSS encryption annoyed cinephiles who imported discs; DeCSS lawsuits became hacker folklore.
Why it still matters
Commentary tracks and deleted scenes turned physical extras into collector culture. Memorable detail: red vs. blue laser branding skirmishes previewed Blu-ray vs HD DVD confusion.
Background
DVDs funded a transition era before broadband streaming, influencing aspect-ratio wars and region-code hacking subcultures.
