MRI Increases Survey Sample Size
Measurement firm MRI has doubled the number of people it surveys each week for its issue-specific magazine readership study, which has been criticized for not having a big enough sample size to be useful to media planners.
MRI—Mediamark Research & Intelligence—said it now surveys 5,000 readers per week, up from 2,500. MRI launched the issue-specific service in June 2007 to supplement its twice-yearly magazine audience report card. Issue-specific measures readership of individual issues of about 195 titles.
