They took every Blu-ray. Not the discs themselves, but the data . The pristine, uncompressed, director-approved transfers. They ripped them. They organized them. And then, to prevent corporate deletion or bit-rot, they uploaded them all to a hidden corner of the Internet Archive.
For decades, if you owned a VHS tape or a DVD, you owned it forever. You could watch it whenever you wanted, regardless of what the studio was doing. Today, the shift to "Digital Ownership" and streaming has introduced a terrifying concept: revocability. Movies and shows are routinely pulled from services like Netflix, Disney+, and Max due to licensing expirations or tax write-offs.
You will not typically find new, studio-released Hollywood blockbusters in full Blu-ray ISO format (complete, bit-for-bit copies of a disc) due to copyright law. The Internet Archive respects the Digital Millennium Copyright Act (DMCA). Uploading a recent Marvel or Disney Blu-ray rip will result in a swift takedown.
