ABSTRACT
Internet survey data collection was introduced at the end of 1980s with email surveys. In the mid 1990s, the World Wide Web (WWW) began to be used for survey data collection and this is the most widely spread form today. In the last few years, we face the integration of technologies resulting in WebTV or digital TV surveys, M-CASI-computer assisted self-interviewing using mobile phone devices, and other integrated solutions (e.g., integrated CATI-computer assisted telephone interviewing systems).
