Digital sport content distributed through a digital network is presumed to have advantages due to the nature of digital content. Diminishing or even no marginal costs should allow for exploitation of current economically non-viable (niche) markets. There is an interest within NOS*NSF to examine the viability of digital sport content exploitation for different types of sport unions. As potential profitability (of the Internet) can be understood only by looking at individual industries and individual companies, this master thesis examines the industry around sport content by economically validating revenue models for four types of sport unions. The question answered in this book is which (combination of) revenue model(s) captures the most economic value for a sport union exploiting digital video content through a website.
