The modern audience may not know what Quinn Martin cliches are, but they include 1) a deep-voiced announcer (often William Conrad) reading the name of the show over a title graphic, 2) show segments broken into Acts (Act I, Act II, etc.), and 3) a lengthy (by today's standards) prologue--also narrated--that gives the whole background of the series for those unfortunate viewers who can't remember the simplest things from week-to-week.
I love to wallow in nostalgia.
