Black Mirror's Nubbin is fictional, not a real device

The "Nubbin" device featured in *Black Mirror* season 7 is entirely fictional, created for the show's narrative. The device, along with its parent company, TCKR Systems, are not real. Promotional efforts included dummy devices sent to influencers. The Nubbin is depicted in two episodes, allowing characters to enter digital spaces. While the device itself is not a real product, similar concepts, like brain-computer interfaces, are under development. Marketing for *Black Mirror* season 7 included a website and social media presence for TCKR Systems. These platforms offered product testing registration, job inquiries, and installation guides to enhance the show's realism.
