I read an article a few years ago talking about the influence of social media on filmmaking. They mentioned the phenomenon of how many films now include bite-sized scenes designed to be shareable as GIFs to help promote the movie (for instance the fistbump scene in the Big Hero 6 film and trailer).
The article named this kind of scene, I thought they called it a "tag", but I've been Googling and I can't find any reference to this concept nor can I remember where I read it. Can anyone help me out? Did I dream it?
