The episode "I Sing the Body Electric" is notable for a number of reasons: it was the 100th episode of the series, and it was one of only four episodes that saw Rod Serling deliver a mid-episode narration. Perhaps most importantly, this is the only episode of the series to be written by this grand master of science fiction. Identify this writer whose most famous book dealt with how the media (television in particular) had become a barrier to reading, but would go on to narrate his own science fiction anthology series from 1985-92. He also wrote a collection of stories that traditionally ends with "There Will Come Soft Rains" and "The Million-Year Picnic".
