You remember the last time you channel surfed? We all do it when there’s nothing good on TV — nothing that holds our attention.
Well, you can’t channel surf with a book. You can skip pages, put the book down, or stare off into space, but that book isn’t changing (unless you have something to write with or a pair of scissors in hand).
That gives the book power. The book controls how you pay attention to it, in a way television can’t.
Because of the links in hypertext, web content is vulnerable, just like television, to channel surfing.
