Questions Unlimited
Questions Unlimited is a company operated by Chip Beall out of Columbus, Ohio, that bills itself as "America's premier supplier of questions and answers for academic competition" and claims to have patented the four-quarter format. This should not be confused with the British company Questions Unlimited, which produces questions and answers for pub quizzes.
Questions produced by Questions Unlimited are generally viewed with disdain by people who enjoy good quizbowl, as they lack pyramidality, have hoses, often have been plagiarized from other sets and ask about completely ridiculous subjects.
The company sponsors the dubious National Academic Championship as well as Quiznet. They also provide questions to local tournaments, such as in Lancaster County, Pennsylvania.
