CIO’s audience is also comprised of more senior-level IT titles than any other measured publication. In the study, CIO magazine ranks number one in both coverage and composition against CIO/CTO/vice president of MIS, IS, IT level titles in organizations with greater than 100 employees. The study also shows that among all publications measured, CIO magazine readers hold the largest information technology (IT) budgets planning to spend the most, on average, on IT products and services in the next 12 months.
