Managing related digital content

Aspects of the present disclosure relate to one or more configured computing systems identifying companion content and supplemental content for a base content. Companion content may include, for example, video adaptations of the base content. Supplemental content may include content referenced or related in subject matter to the base content. Information regarding companion content may be utilized to enable a user to interchangeably or synchronously present either a base content (e.g., an eBook or audio book) with the companion content (e.g., a movie adaptation). Information regarding supplemental content may be utilized to present the supplemental content during consumption of a base content, or to save supplemental content for later viewing.
