Alien Worlds was a syndicated radio show created by radio personality Lee Hansen. It aired 26 half-hour episodes between 1978 and 1980, becoming well known for its realistic sound effects, high production values and documentary style of dialog. The science fiction show was first syndicated by Watermark Inc. after Lee Hansen was hired as their creative director. After advancing the concept of an action-adventure dramatic radio series, Lee began developing the concept in the fall of 1978. Watermark premiered the first episode, "The Sun Stealers", on January 7, 1979. The series gained popularity thanks to its relatable characters, full symphonic soundtrack, realistic sound effects, high production values and documentary style format. Eventually over 500 US FM radio stations, along with stations in New Zealand and Australia aired the series.
