He developed a series of standards for international variants that ensured they mirrored the British original closely. For example, all hosts were required to appear on-screen wearing Armani suits, as Tarrant did in the UK; producers were forbidden from hiring local composers to create original music, instead using the same music cues used by the British version; and the lighting system and set design were to adhere faithfully to the way they were presented on the British version. Some of Smith's rules have been slightly relaxed over the years as the franchise's development has progressed. Dutch company 2waytraffic ultimately acquired Millionaire and all of Celador's other programmes. Two years later, Sony Pictures Entertainment purchased 2waytraffic for £137.5 million. Sony Pictures Television currently owns and licences the show's format, while Disney–ABC Domestic Television, the Walt Disney Company's in-home sales and content distribution firm controls the US version independently of Sony. Gameplay Rules A group of contestants on each episode play a preliminary round called "Fastest Finger First". All are given a question by the host and four answers which must be placed within a particular order; in the first season of the original version (1998) and the first four seasons of the Australian version (1999–2002), contestants have to answer a multiple-choice question. If any contestants are visually impaired, the host reads the question and four choices all at once, then repeats the choices after the music for the round begins. The contestant who answers correctly in the fastest time goes on to play the main game. In the event that no one gets the question right, another question is given; if two or more contestants answer correctly but with the same time, they are given a tie-breaker to determine who will move on. This round is only used when a new contestant is being chosen to play the main round, and can be played more than once in an episode among those remaining within the group seeking to play the main game. In celebrity editions, the round is not used; celebrities automatically take part in the main game. Once a contestant enters the main game, they are asked increasingly difficult general knowledge questions by the host. Each features four possible answers, to which the contestant must give the correct answer. Doing so wins them a certain amount of money, with tackling more difficult questions increasing their prize fund. During their game,
