A method, system, and computer program product is disclosed that evaluates the characteristics of a new content source with respect to subscriber profiles. The subscriber profile attributes are evaluated and weighted algorithmically to produce an “inference score” that is a measure used to predict the interest that subscribers may have with respect to the new content. If the inference score is significant enough (e.g., above a certain threshold value), then the service provider can take measures to inform those subscribers deemed to have a high level of interest in the new content of its existence, e.g., by sending a simple notification to the subscriber with a response link for setting up a subscription.
