Definition from Wikipedia: “Crossmedia (also known as Cross-Media, Cross-Media Entertainment, Cross-Media Communication) is a media property, service, story or experience distributed across media platforms using a variety of media forms.”
My example: a book, a best-seller book, that comes with a soundtrack composed by the author/writer. To read and listen at the same time. And to go deeper and deeper into the story.
The Shadow of the Window, a best-seller book from Carlos Ruiz Zafón
