'Black Mirror' references and clues that hint towards a shared universe

Netflix's Black Mirror is a massively popular dystopian anthology series that showcases the downfalls of over-relying on modern technology. What many fans do not know, is that all the episodes in the show are actually a part of the same multiverse. While each episode has its own theme, message, and unique technology, they are all interconnected via covert references.

In fact, every episode of Black Mirror has multiple hidden references that can link back to past episodes or give a glimpse into possible future episodes. The maker of Black Mirror, Charlie Brooker, enjoys linking the various episodes of the show to create a secret interconnected multiverse. Here are some popular connections and references that prove that Black Mirror's episodes all take place in a shared universe.
