'Jeopardy!' was conceived as a way to earn back skeptical audiences' trust

In the wake of the ‘50s scandals, networks were reluctant to greenlight new quiz shows.

It eventually became the top-rated quiz show in history with 23 million viewers.

The first cast members were relatively unknown 'enlightened amateurs'

“SNL” producers aimed to cast relative newcomers for the show’s first season, convinced that amateurs would infuse the show with the countercultural spirit Lorne Michaels envisioned.
