Instead of conducting a survey of a selected group of consumers in a haphazard way and that will no longer be applicable once the investigation is completed, one may want to understand what influences a market on a regular basis. Panels stand out against surveys because they provide a dynamic view of the observed object: in a group of consumers or retailers, the panel is a fixed sample that regularly provides information to a specialized company.
The panels are already quite old having been born shortly before the 1929 crisis in the United States of America to reach a quarter of a century later in Europe. In any permanent sample, when we question about any subject in order to define its state at a given time, the repetition of the observation and evolution of this state constitutes a panel.
For "USA", the panel of Market Research Corporation of America is stronger than ten thousand (10,000) households against France where the figures are lower; the operation is managed by the SECODIP. (French Society for the Study of Consumption, Distribution and Publicity) to which we will be interested.

On another level, surveys are conducted every two months and promotional activities and have a good chance not to be identified. [...]
