Abstract:
An important challenge faced by media broadcasting companies is how to allocate limited advertising space between upfront (forward) contracts and the spot market (referred to in advertising as the scatter market) to maximize profits and meet contractual commitments. We develop stylized optimization models of airtime capacity planning and allocation across multiple clients under audience uncertainty. In a short-term profit maximizing setting, our results provide insight for capacity planning decisions upfront and during the broadcasting season. Our results suggest that broadcasting companies should prioritize upfront clients according to marginal revenue per audience unit. We find that accepted upfront market contracts can be aggregated across clients and served in proportion to the audience demanded. Closed-form solutions are obtained in a static setting. These results remain valid in a dynamic setting, when considering the opportunity to increase allocation by airing make-goods during the broadcasting season. Our structural results characterize the impact of contracting parameters, time, and audience uncertainty on profits and capacity decisions. The results hold under general audience and spot market profit models. Overall, we find that ignoring audience uncertainty can have a significant cost for media capacity planning and allocation. © 2010 INFORMS.
