Each MediaMatrix page covers one vendor category, e.g. Clinical Services.  Linked within a major category are several sub category pages; such as Clinical Trial Management, Clinical Packaging, Data Management Software, etc. In addition each page contains a drop-down News box. The News Box contains links to news stories, research reports and press releases important to each category or discipline. To date we've identified 13 major product and service categories, 12 desciplines and over 180 sub categories. The body of each page contains the names of the publications marketers would be interested in.  Click here for a listing of all the MediaMatrix Pages.
