A reach curve estimates the number of unique people that see an advertisement as a function of the number of advertising impressions that are purchased on an advertising network. A pairwise union overlap model can be used to compute a reach surface based on the reach curves of individual publishers. Such a reach surface can then be used to estimate the total number of unique people that can be reached for any arbitrary allocation of spend across multiple publishers.
