Alien Worlds (Radio) (ep19/20) 1979 The Infinity Factor

Alien Worlds was a syndicated radio show created by radio personality Lee Hansen. It aired 26 half-hour episodes between 1979 and 1980, becoming well known for its realistic sound effects, high production values and documentary style of dialog.

Background
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. Between 1979 and 1980, 26 half-hour programs were broadcast at various times on weekends, where they gained favorable worldwide press acclaim. Alien Worlds was soon heard on a weekly basis by millions of fans and was eventually carried by over 1500 top-rated FM radio stations worldwide. The series' sponsor was Peter Paul, Cadbury which advertised Cadbury Caramello chocolates touting their caramel centers.

Four additional episodes were produced but never aired. The show was previously repeated on Sirius Satellite Radio, and on the Alien Worlds website (which since closed). The series is being developed for 3-D animation for television and DVD release.
