A method is disclosed for monitoring the audience of an advertisement over a content distribution system, the advertisement comprising an advertising message associated with an audio content. The method comprises: inserting, within the message, an advertising identifier associated with the advertisement and distributing the audio content with the advertising message to a user of the content distribution system; at a first user device configured to receive the audio content, playing the audio content with the advertising message; at a second user device connected to the first user device and configured to communicate with a data collection server over a data communication network, retrieving a customer identifier uniquely associated with the user; and, during or after playing, sending by the second user device the customer identifier and the advertising identifier extracted from the advertising message to the server to monitor the audience of the advertising message.

In one aspect, an example method to be performed by a vehicle-based media system includes (a) receiving audio content; (b) causing one or more speakers to output the received audio content; (c) using a microphone of the vehicle-based media system to capture the output audio content; (d) identifying reference audio content that has at least a threshold extent of similarity with the captured audio content; (e) identifying visual content based at least on the identified reference audio content; and (f) outputting, via a user interface of the vehicle-based media system, the identified visual content.

An example apparatus to monitor media that is presented via a mobile device includes: an application monitor to determine when media presentation software is being executed by the mobile device; and a metering information collector to collect at least one of a signature or a code of the media presented by the media presentation software based on the media presentation software being executed by the mobile device.

Techniques for regional viewership predictions of broadcast events such as live broadcast professional sporting events. The techniques can make the predictions without a direct response variable such as regional viewership data for training a prediction model. Instead, in one technique, demand information for a good or service is used. From the demand information, a derivative demand for the good or service relative to a normal demand is determined. A regression framework is used to learn relationships between the derivative demand for the good or service and features of past live broadcast sporting events. This results in a matrix of feature weights. A non-parametric mixture framework is then used to find a set of feature weights that can be applied to features of future broadcast events to generate regional viewership predictions for the events.

Methods and apparatus to calibrate media ratings based on return path data are disclosed. An apparatus includes a processor and memory including instructions that, when executed, cause the processor to: determine an initial rating for the media provided in a first geographic area based on return path data (RPD) tuning information obtained from RPD devices in subscriber households in the first geographic area; determine a first panelist rating for the media provided in a second geographic area based on first panel tuning information obtained from first metering devices in a first subset of panelist households in the second geographic area; determine a nonsubscriber calibration factor based on the first panelist rating; and determine a final rating for the media in the first geographic area by modifying the initial rating based on the nonsubscriber calibration factor.

A method and system for digital marketing and the provision of digital content allows a user to express, using an application executed on a computing device while a piece of content is being broadcast using an analog or digital signal by an analog or digital radio or television station system, an interest in the broadcast piece of content that is communicated to a backend system. The backend system selects an end point destination that is a pointer to further digital information associated with the broadcast piece of content and communicates the end point destination for the broadcast piece of content to the user who can access the digital information.
