There was a time, early in its development, when all forms of research conducted over the Internet were simply labeled online research. Thanks to the near-ubiquitous nature of the Net and the reduced cost of database applications, online research continues to evolve in the direction of panel-based research. Unlike many CATI/CAPI-based systems, through which data is collected once for a specific purpose, research conducted across a managed panel allows all of the respondent's data to be used for future purposes. As panel-based research services continue to grow, a number of opportunities become of even greater value to marketers.
