Abstract: Automatically conveying content acquisition opportunities to users following detection of proximity to interactive signage. This may entail detecting proximity of a portable device to an interactive sign. The interactive sign is associated with a content item, such as music or a video that may be playing on or with the interactive sign. The portable device is associated with a user and has a user identifier. A unique identifier is generated in association with the proximity detection, which correlates the user identifier and the content item. The unique identifier is transmitted to a content site, which has some form of identification of both the user identifier as well as the corresponding content item. The content site then conveys to a device separate from the portable device an opportunity for the user to acquire a digital representation of the content item.

Abstract: Delivery of advertisements to participants in communications using a packetized telephony protocol (e.g., VoIP). This may comprise identifying a keyword used in a telephone conversation between parties, at least one of which uses a packetized telephony protocol device to participate in the telephone conversation. Then, a particular advertisement that includes image content is correlated to the telephone conversation based upon identification of the keyword. Delivery of the particular advertisement is prompted, preferably to the packetized telephony protocol device used by one or more of the parties to the telephone conversation. The delivery accommodates display of the image content for the particular advertisement without interrupting the telephone conversation between the parties.
