Hi there Enrique, welcome to the list I don't have stats directly, but have found the following two sites, both of which are industry oriented, useful in teaching about online Market Research. They might help http://cyberatlas.internet.com/ Primarily a site that gives LOTS of the stats which MR and opinion polls discover; however there might be material that is on the process of MR online itself. Lots of free basic info, ads for the very expensive detailed reports beloved of market research firms. http://www.quirks.com/ "Marketing Research Review" An online trade magazine, with good short articles, and resources; has had a lot of good discussion for and against online MR. I would imagine it has some of the info you need. Matthew Allen Curtin University of Technology
