SYNCHRONIZING DIGITAL CONTENT

Aspects of the present disclosure relate to one or more configured computing systems identifying when decoupled content includes a companion content pair (e.g., a first content and a second content) that can be synchronously or interchangeably presented. Further, aspects of the present disclosure relate to notifying a user of the availability of companion content. Notifications can be displayed to a user at any number of notifications triggers that indicate the user may be interested in acquiring companion content. Further, notifications may correspond to an offer to acquire at least a portion of companion content, such as a trial of the companion content. If a user accepts such an offer, synchronization information may be used to begin presentation of the companion content from a last consumed position of a corresponding first content.
