If there's anything more satisfying for the quizzer than getting the correct answer to a question, then it must be getting the correct answer from a fragment of information rather than a complete question. Sadly, the only televised format which allows this sort of satisfaction is the 'starters-on-the-buzzer-followed-by-bonuses' format of 'University Challenge'. There are two drawbacks to this. The first is that, even if you're a student, you only get one chance to take part in 'University Challenge', or at the most two chances if you move to a different university for postgraduate study. The second is that, if you're not a student, you don't get a chance to take part at all.
The organisation formerly known as British Academic Quiz Tournaments (BAQT) addressed the first drawback for four years, by organising tournaments comprising 20-minute matches (using the familiar format of starters on the buzzer followed by bonuses) which any student could take part in for as many years as they remain a student. Starting in 2002, the same organisation known as BuzzerQuiz began addressing the second drawback, by running the same sorts of tournaments for anyone, student and non-student alike, who wants to take part.
