1. Conventional bookmarks are ineffective because readers remove them when opening a book, making any advertising on them invisible, and often lose them inside the book. 2. The AutomaticBookmark is a flexible bookmark that stays on the page being read even if the book closes accidentally. It folds to fit books of different thicknesses as pages are turned. 3. The AutomaticBookmark provides constant visual exposure to advertising through every page turn, allowing for subliminal cumulative marketing effects over the entire reading of a book. It is a customizable business card that will not get lost inside the book.
