An end-to-end automated management system facilitates generation of advertisement proposals, and purchase orders, over one or many media outlets and stations. Once an advertisement proposal is purchased and inserted into a traffic management and billing system, near-real-time performance feedback about the advertisements can be obtained from media consumers through a media presentation application presenting the advertisement, via a social media service, or the like. The consumer feedback and other performance factors, which can be received concurrently with airing of an advertisement, can be considered in determining whether a particular advertisement or an advertising proposal as a whole, is effective in meeting purchaser requirements. Advertisement copy can be changed according to the proposal parameters, without purchaser intervention, to provide near-real-time responsiveness to consumer feedback.
