A method, system and computer-readable storage medium provide for managing stranded assets of a customer service call center. The system includes an interface component that identifies an opportunity event of an established customer service session initiated by a user that is in a waiting queue for a customer service representative. The system includes an ingestion component that ingests one or more characteristics of the opportunity event that characterize at least one of: (i) the identity of the user; (ii) subject of the established customer service session; and (iii) situational context of the user. The system includes a correlation component that correlates the one or more ingested characteristics and an estimated duration of the waiting queue with at least one transaction-related content item. The system includes a publishing component that publishes a selected transaction-related content item via the established customer service session to the user while in the waiting queue.
