Because of movie transitions from scene to scene leading to slide projectors with transitions from scene (slide) to scene leading to powerpoint-like presentations using digital slides iwth transitions from scene to scene? People are used to scene transitions going back a long time (maybe even thousands of years in the manner of theatre scenes/transitions). Slides make sense to me in that regard at least. This is all just a huge, un-researched, wild guess, of course.
