Princeton, NJ (January 11, 2005) – PERQ/HCI recently released AIM™ Version 5.5 with new functionality for planners at agencies and publishers. New features make AIM the most comprehensive healthcare planning solution available. PERQ/HCI and SRDS are pleased to announce that now, with one click, AIM users can link directly to SRDS publication listing data and JARScan™ pharmaceutical ad images from within all AIM applications.

Those who subscribe to both AIM and the SRDS Business Publication Advertising Source® can access detailed, continuously updated SRDS information. Kathleen Henderson, PERQ/HCI General Manager and Senior Vice-President, states: “Media planners will benefit from simultaneous access to in-depth data from PERQ/HCI in conjunction with the essential SRDS data for effective planning.” Henderson continues, “This collaboration between VNU sister companies means easier analysis of information, streamlined decision-making and increased productivity for our shared clients.”

Agency and publisher clients currently use AIM to evaluate healthcare journal performance (using FOCUS™ and Media-Chek®/APEX™ data), perform competitive audits and create and maintain ad schedules. Subscriber feedback is the foundation for these enhancements to make the system more efficient and powerful.

Bernadette Cognac, Director of Client Services for SRDS, explains: “Now PERQ/HCI and SRDS subscribers can link to essential SRDS information, including comprehensive advertising rates, circulation figures, contact information, and issue and closing dates. Listings also supply direct links to ABC and BPA publisher statements, publication Web sites and online media kits.”

Subscribers to both AIM and JARScan will benefit from direct links to pharmaceutical ad images from within AIM. Pharmaceutical ads from over 600 medical journals are coded and scanned by PERQ/HCI for easy retrieval and analysis. This searchable online database eases the process of performing competitive analysis and adds impact to new business presentations.
