The main objective of this study was to quantify the economic contribution of copyright-based industries in Tanzania by estimating their value-added contribution to GDP, share of national employment, and revenue generated from foreign trade. In addition, the study aimed at providing material to assist in the formulation of adequately informed policies in order to improve the operation of the creative sector in the country. The WIPO Guide (2003) was used as a methodological basis for this research. The Guide classifies the copyrightbased industries into core, interdependent, partial, and non-dedicated support industries (NDSIs). The study depended mainly on secondary data covering the years 2006-07 to 2009-10. The main sources of these data were government departments and other related organizations, including the National Bureau of Statistics (NBS), Tanzania Revenue Authority (TRA), Business Registration and Licensing Agency (BRELA) and the Copyright Society of Tanzania (COSOTA), which is the only collective management organization (CMO) that also serves as a copyright office.
