The producers considered the revival a merger of "What's My Line?" and its 1950s spinoff, "I've Got a Secret," which resulted in noticeable changes from the original. As with "Secret," contestants frequently demonstrated their skill or product after the game. Bruner, and later Blyden, would preface the demonstrations by asking Lloyd Gross, who directed most of the editions, "Lloyd, would you open the curtains, please?" Dollar signs for "no" answers were replaced by sequential numbers. Mystery guest rounds were no longer scored and simply ended with a correct guess or when time ran out.
