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. After the successful airing of a backdoor pilot movie, Warner Bros. commissioned the series as part of the second-year schedule of programs provided by its Prime Time Entertainment Network (PTEN). It premiered in the United States on January 26, 1994, and ran for the intended five seasons. Describing it as having "always been conceived as, fundamentally, a five-year story, a novel for television," Straczynski wrote 92 of the 110 episodes, and served as executive producer, along with Douglas Netter.
