Once upon a time, in an era before DVRs, VCRs, and home-video box sets, television broadcasters couldn’t count on viewers watching every single episode of a TV series. For the producers of those series, one of the quickest and dirtiest ways to bring newcomers up to speed was a practice borrowed from the medium’s predecessors in radio and film serials: A spoken-word intro neatly summarizing the program’s premise. (“It’s a bird! It’s a plane! It’s Superman!” and “Who knows what evil lurks in the hearts of men?”)
On the small screen, the device found its gold standards during the late ’50s and mid-’60s, when the voices of Rod Serling (“You’re traveling through another dimension, a dimension not only of sight and sound, but of mind”) and William Shatner (“Space: The final frontier”) primed audiences for the latest installments of The Twilight Zone or Star Trek. Introductory narration at its very best, these lead-ins evoked the spirit and tone of each show, piquing interest and engaging the imagination with poetic crispness. But there is, unheard by the average viewer (because they’re too busy hitting fast-forward), another type of voice-over intro, that is just as real, but not as brightly written. These intros exposit, they ramble, and they get bizarrely detailed—but they’re also lovable in their long-winded ways. (And even when they’re not actually that long, they still say too much.)
