Babylon 5 is an American space opera television series created by writer and producer J. Michael Straczynski, under the Babylonian Productions label, in association with Straczynski's Synthetic Worlds Ltd. and Warner Bros. Domestic Television.
Set between the years 2258 and 2281, it depicts a future where Earth has sovereign states, and a unifying Earthgov. Colonies within the solar system, and beyond, make up the Earth Alliance, and contact has been made with other spacefaring races. The ensemble cast portray alien ambassadorial staff and humans assigned to the five-mile-long Babylon 5 space station, a centre for trade and diplomacy. Described as "one of the most complex programs on television," the various story arcs drew upon the prophesies, religious zealotry, racial tensions, social pressures, and political rivalries which existed within each of their cultures, to create a contextual framework for the motivations and consequences of the protagonists' actions. With a strong emphasis on character development set against a backdrop of conflicting ideologies on multiple levels, Straczynski wanted "to take an adult approach to SF, and attempt to do for television SF what Hill Street Blues did for cop shows."
