Science fiction first appeared on a television program during the Golden Age of Science Fiction. Special effects and other production techniques allow creators to present a living visual image of an imaginary world not limited by the constraints of reality.
In general, science fiction series are subject to the same financial constraints as other television shows. However, high production costs increase the financial risk, while limited audiences further complicate the business case for continuing production. Star Trek was the first television series to cost more than $100,000 per episode, while Star Trek: The Next Generation was the first to cost more than $1 million per episode.
