Earlier this year, we completed our 2009 Feedback Survey (thanks to all who participated!). We asked our users (who conducted web-based surveys) to list the providers of online sample they had used in the previous 12 months. This was asked as an open-end question, with no prompting regarding potential sample providers. The text of the question and the percent of respondents naming each firm are given below (multiple responses allowed; firms mentioned by fewer than 3% of respondents not displayed).
What providers of Online Web Sample/Online Panels did your firm mainly use in the previous 12 months? (List up to six).
