In order to allow marketers to ascertain the reach of specific marketing campaigns and their success in making contact with targeted demographics, Mediamark Research and Intelligence has doubled the number of people surveyed in their issue-specific magazine readership survey, reports Media Daily News.

MRI's research will yield more detailed and frequent data than its usual bi-annual overall survey of consumer magazines. Critiques say the decision to boost the number of participants is in response to clients who complained that the study wasn't large enough to produce the detailed data required by advertising clients.

In another attempt to reassure unhappy clients, MRI acquired Starch Communications, a company that focuses on the reception and impact of ads, with the goal of providing detailed information on issue-specific individual print ads. The company has also begun to incorporate age, education, and income data into their issue-specific study.
