The Origins of the Star Trek Phenomenon
The Origins of the Star Trek Phenomenon: Gene Roddenberry, the Original Series, and Science Fiction Fandom in the 1960s

Summary
From the back cover
Star Trek became one of the most popular television series, not only in the Unites States but the world, in the latter half of the twentieth century. The original series aired from 1966 to 1969, a momentous time of change in American history. During the middle to late sixties, American society was responding to recent civil rights legislation, underlying Cold War tensions (especially those associated with Vietnam), and evolving gender roles. Even though the accepted notion that the series embraced progressive thought drawn from Lyndon Johnson's ideals of the Great Society and one of racial, gender and economic equality, Star Treks plots and scripts often contradicted this ideology intentionally and unintentionally. Star Treks inconsistency, to some degree, stemmed from some of its writers immersion in conventional points of views as evidenced in the scripts they wrote. However, some of the most glaring inconsistencies came from Roddenberry's influence on the series.

Over the development of the series, the meaning and liberal-humanist elements within Star Trek were initially contributed by others on the production team; then fans took those messages and created a worldwide phenomenon that celebrated those ideas. Ultimately, it was the fans who infused Star Trek and the series fan community with their collective hope and optimism for the Human race.
