A questionnaire network makes it possible to create, disseminate, conduct questionnaires or surveys on mobile handsets and to collect results for processing and storage. The questionnaire network is powered by a questionnaire creation tool and a questionnaire trading system. A questionnaire trading system for QTime makes it possible for producers of QTime, such as carriers, and consumers of QTime, such as product manufacturers and advertising companies, to buy or sell QTime in bulk and to trade in QTime as a commodity. In one embodiment, supplementary information and preambles that are part of a questionnaire are captured in audio form using the questionnaire creation tool and are stored selectively along with the questionnaire in a carrier's questionnaire repository or separately at a hosted repository.
