Thebe

Overview
Thebe is an augmented reality device invented by Terrance Experimental Robotics that took the form of a chip inside the brain. It was a financial success upon the first week, with over 4 million chips sold. By the fourth week, sales had dropped to 145, and for a good cause. Thebe caused cataclysmic brain damage, including but not limited to hallucinations, paranoia, hysteria, memory distortion, inability to process time passing correctly, inability to process spatial dimensions, and comatose states. Over 140,000 deaths were linked to the device. TER was sued for this, and they almost went completely bankrupt. They became a computer repair company for almost 34.5 years before returning to bigger projects.
