When this episode airs in repeats, the name of the Muzak Corporation is masked out. The actors lips move, but the sound is cut. It is still easy to tell what the line is due to context. While it has come to be a generic term for inoffensive music (as "Kleenex" has for facial tissues), the Muzak Corporation is a real corporation as of 2020.
Mr. Alsop is named for Joseph Alsop, a syndicated columnist and closeted homosexual.
Mr. Corwin is named for Norman Corwin, considered the greatest of radio playwrights.
