Cross media targeted message synchronization

A computer system, comprising:

• a computer processor;
• and
• a computer-readable storage medium storing computer program engines configured to execute on the computer processor, the computer program engines comprising:
• a video alignment engine configured to determine that an advertisement media event aired during an airing of a television media event broadcasted by a time based media source;
• a social media alignment engine configured to identify a plurality of social media content items broadcasted by a social media source that have been programmatically assessed to be relevant to the time-based media event, the social media source different from the time-based media source,
• wherein the identifying comprises determining, for each of the plurality of social media content items, a confidence score indicative of a probability that the candidate social media content item is relevant to the television media event;
• an audience population engine configured to determining a population of authors comprising authors of the plurality of social media content items, and filtering the population of authors based on author specific information stored in a social media author store and one or more cross-medium targeting rules associated with the advertisement media event, each cross-medium targeting rule specifying different parameters for targeting authors of social media content items broadcasted by the social media source who have been exposed to the advertisement media event broadcasted by the time-based media source;
• and
• a message interface engine configured to send to computing devices associated with the filtered population of authors a message related to the advertisement media event.

A non-transitory computer readable storage medium comprising computer program instructions that, when executed by a processor, cause the processor to:

• determine that an advertisement media event aired during an airing of a television media event broadcasted by a time based media source;
• identify, using a social media alignment engine operating on a computing device, a plurality of social media content items broadcasted by a social media source that have been programmatically assessed to be relevant to the time-based media event, the social media source different from the time-based media source,
• wherein the identifying comprises determining, for each of the plurality of social media content items, a confidence score indicative of a probability that the candidate social media content item is relevant to the television media event;
• determine a population of authors comprising authors of the plurality of social media content items;
• filter the population of authors based on author specific information stored in a social media author store and one or more cross-medium targeting rules associated with the advertisement media event, each cross-medium targeting rule specifying different parameters for targeting authors of social media content items broadcasted by the social media source who have been exposed to the advertisement media event broadcasted by the time-based media source;
• and
• responsive to the airing of the advertisement media event, send to computing devices associated with the filtered population of authors a message related to the advertisement media event.
