Deaf Diode Jackson is an automated personality created by Doctor 0 before the Great War as part of a competition called to live by the United States government. The aim of the competition was it to create an AI, which could work as a radio host without an own ideology to spread the propaganda of the government. This competition was won by Robert House and his AI, which became later Mr. New Vegas. Out of a fit of rage Doctor 0 renamed his creation Deaf Diode Jackson and repurposed it as an Anti-Robert House-AP. Its new function was it to take over Houses's technology and so to destroy the "House-Empire" from within. For this purpose Doctor 0 integrated Deaf Diode Jackson into the X-66 Hexcrete Archipelago, which is in fact a signal-amplifier, so that he had the range to archieve his goal even from the isolated location of the Big MT.
Unfortunately the security measures put up by Robert House made it impossible for Deaf Diode Jackson to actually fulfill his purpose up to the point, when the Courier installed the Securitron Mark II operating system. This created a small gap, which Deaf Diode Jackson used to slip into the technology, which was sealed in Vault 21 by Robert House. After more than 200 years of waiting Deaf Diode Jackson got his chance to take revenge on the AI, which ruined his artificial life, Mr. New Vegas.
