Patent attributes
An advertisement system includes an advertising manager that receives a content-event indicator, which indicates playback of an advertisement for viewing on a first display screen at a media-playback device or indicates playback of recorded content that includes advertisements. The advertising manager can determine an optimal time offset as a duration of time before or after playback of an advertisement to the start of an event that is associated with the advertisement for viewing on a second display screen at a mobile device. For recorded content, an optimization schedule is determined that replaces and time-shifts advertisements during playback of the recorded content. The advertising manager can also determine a fulfillment criterion for a product or service based on latency constraints to indicate a duration of time within which fulfillment of the product or service is expected when offered as a second advertisement corresponding to a first advertisement.
