Over the past 70 to 80 years, the research industry has seen a lot of changes in the data collection methods it uses. Basic data collection methods (mail survey, telephone interviewing, mall intercepts, and personal interviewing) were developed, used, evaluated, and improved upon. With the advent of computer and communications technologies, researchers developed computer-assisted telephone interviewing (CATI), computer-assisted personal interviewing (CAPI), disk-by-mail surveys, and fax surveys as new data collection methods. With the growth of the Internet and computer networks, we’re seeing a steady stream of research into the use of e-mail as a data collection tool, along with Web-based surveys.
