"Assignment: Earth" was originally intended to be a back door pilot episode for a spin-off TV series from Star Trek: The Original Series. The series never made it into production but Gary Seven has subsequently been featured in numerous stories in other spin-off media. Assignment: Earth finally became a series of sorts in 2008 when IDW Publishing produced a comics miniseries inspired by the original idea of a TV series: Star Trek: Assignment: Earth, detailing the adventures of Gary Seven in the late 1960s and early 1970s.
