The concept or term "Wayback machine" has been adopted in popular culture as a convenient way to introduce issues or events of the past, often employing the original line "Sherman, set the Wayback machine to ...". This introduction was used by the character Kevin Flynn in the film "Tron", for example. As in the original cartoon, the Wayback Machine is often invoked to suggest the audience follow the narrator back to the past. Frequently such visits to the past are trips of nostalgia, remembering times, places, or things of the not-so-distant past.
