7. 'Star Trek'
"Space...the final frontier" may be the single most well-known phrase in popular culture, recognized even by those who wouldn't sit through an episode of "Star Trek" if you paid them a million quatloos. With Captain Kirk's bold, expositional words and that far out theme song accompanying the Enterprise's race through space, "Star Trek" instantly set itself apart from other TV sci-fi shows in both its serious tone and endless imagination. The first ten seconds or so of the show's opening are still synonymous with the term "science fiction" for many fans.
