There is a particular silence that only a quiz show can produce. A question has been asked, a clock is running, and several million people who will never meet the contestant are quietly answering along at home. Broadcasters worked out how to manufacture that silence nearly ninety years ago, and they have been selling it ever since.

Radio learns to ask

The format arrived partly by accident of economics. Radio in the 1930s was hungry for programming that did not require an orchestra or a cast of actors, and a man with a list of questions was about as cheap as broadcasting got. Professor Quiz reached CBS on 9 May 1936 and is generally credited as radio's first true quiz programme. Its prizes were modest by any standard, the winner taking twenty-five silver dollars and the runner-up fifteen, but the show had found something worth more than a prize fund. Listeners could post in questions of their own, and some of those questions went on air. The audience was inside the programme rather than beside it.

Information Please followed in 1938 with a more clubbable version of the idea: a panel of conspicuously well-read experts, and listeners invited to try to stump them. Dr. I.Q. arrived the next year with a roving announcer working the stalls of a theatre. Within a handful of years the quiz had already split into the two strains that still sit side by side today. One is a test of a person, watched to see whether they can do it. The other is a game with a person in it, watched to see what happens to them.

Television raises the stakes

Television inherited the format and then did something radio had never dared. In the summer of 1955, The $64,000 Question took its name and its structure from the radio show Take It or Leave It, where the top prize had been sixty-four dollars, and multiplied the money by a thousand. The multiplication was the entire point. A contestant who had already banked a small fortune stood in a glass isolation booth, headphones on, sweating under the lamps, deciding whether to risk all of it on one more answer. Ratings were enormous, imitators appeared within months, and the American networks discovered that arithmetic could carry a whole evening.

Twenty-One premiered on NBC in September 1956, hosted by Jack Barry. Its first outing was, by the later admission of its own producers, a dismal failure: the two contestants played honestly, played badly, and the sponsor was not pleased. What the producers decided to do about that has shaped the way broadcasters are regulated to this day.

The trouble with a script

Herb Stempel, an army veteran of modest means, had been the audience favourite on Twenty-One until the production decided his run should end. On 5 December 1956 he was instructed to miss a question he could comfortably have answered, and he lost to Charles Van Doren, a young English instructor from a celebrated literary family at Columbia. Van Doren was photogenic and hesitated in exactly the right way, apparently wrestling answers out of the air while the nation held its breath. By the end of his run he had won $129,000; Stempel had taken $69,500 before his scripted defeat. Both men, it later emerged, had been coached.

The unravelling began somewhere else entirely. Dotto was pulled off the air in August 1958 after a waiting contestant found a notebook containing another contestant's answers, and by the end of that year the big-money quizzes had been cancelled one after another. A House subcommittee chaired by Representative Oren Harris opened hearings in October 1959. On 2 November, Van Doren testified on national television and said that he had been involved, deeply involved, in a deception. Congress responded by amending the Communications Act; President Eisenhower signed the bill on 13 September 1960, and the provision codified at 47 U.S.C. section 509 made it an offence to fix a contest of knowledge or skill with intent to deceive the viewing public. Robert Redford's 1994 film Quiz Show later did more than anything else to keep the names in general circulation.

A different tradition

Britain came at the quiz from another direction, because its dominant broadcaster carried no advertising and had no appetite for handing out money. Cash prizes arrived with commercial television. Take Your Pick, which had been running on Radio Luxembourg since 1952, moved to the screen on 23 September 1955, a day after ITV launched, and is generally described as the first British game show to offer cash. For years afterwards the British quiz kept a faint embarrassment about prizes, and compensated by taking the questions far more seriously than anyone else did.

That instinct produced the two programmes that define the national style. University Challenge began on ITV on 21 September 1962, adapted by Granada from the American College Bowl, with Bamber Gascoigne asking questions no sensible person could be expected to answer and students buzzing in anyway. The BBC revived it in 1994 with Jeremy Paxman in the chair, and Amol Rajan took over in 2023. Mastermind first aired on BBC1 on 11 September 1972. Its creator, Bill Wright, had been interrogated by the Gestapo as a prisoner of war, and the black chair under a single lamp in an otherwise dark studio is a direct inheritance from that memory. Contestants take two minutes on a specialist subject of their own choosing, then two minutes on anything at all, and the quizmaster's line when the buzzer cuts across a question, that he has started so he will finish, became one of the most quoted sentences in British television.

How the format came back

The American recovery took a quieter route, away from the giant jackpot and towards the daily habit. Daytime and syndicated formats rebuilt trust by making the game itself the star rather than the contestant, with modest stakes, fixed rules and a returning champion who was plainly just very good at this. Behind the scenes the industry acquired the machinery it had previously done without: independent adjudicators, sealed question banks, staff forbidden from meeting contestants, compliance officers who exist precisely because 1959 happened.

Big money only returned once that machinery could be seen. Who Wants to Be a Millionaire? premiered on ITV in September 1998 and was exported to more than a hundred territories, and its cleverest move was to televise the safeguards alongside the drama. The lifelines were rules made theatrical. The walk-away option, the contestant's own agonising hesitation, the host refusing for an unbearable stretch to say whether the answer was right, all of it advertised that nobody backstage was steering the result. A format destroyed by secret help had been rebuilt around help you could watch.

What survived every twist is the thing radio found first: a question, a pause, and the private satisfaction of knowing the answer a second before the person being paid to know it. Prizes have gone up and down, scandals have come and gone, and that pause has never once loosened its grip.
