The first teaser trailer for Black Mirror season 6 has finally been released, and there’s a reason why it took four years to finally happen. The first season of Netflix’s dystopian series was released in 2011 and shot to popularity with its dark anthology-style storytelling. Black Mirror continued its success and four more seasons were created with Charlie Brooker at the helm, and released in 2013, 2016, 2017, and 2019, as well as the interactive movie Bandersnatch in 2018. Black Mirror twists future life with innovative technology to create dark stories that are chillingly not too improbable which has been highly praised in the past.
