One aspect of The Twilight Zone franchise that may not be as well known is that its content extended beyond the classic television series, giving rise to a wide range of comics, books, and special publications.
One of these was The Twilight Zone Magazine, which during its eight years of existence made room for literary stars like Stephen King, Peter Straub, and George R. R. Martin.
