I may have just seen the future of book promotion, and if so, then it is TitlePage TV. It wasn't easy to run across; I did, because I was paying attention to the April 22 PaperCuts blog (which is a New York Times book blog). Once I got past the baffling book multimedia show for a book by Sloane Crosley called, I Was Told There'd Be Cake (don't get me wrong -- it was a wonderfully-produced show, but I was at a loss to figure out its message), I gleefully found the TitlePage TV show (hosted by editor and novelist Daniel Menaker).
Way to go, Daniel! Your show looks as nice as anything you might see on broadcast TV, and I'll bet its attracting more prospective guests than you have the time to interview.
Web-based TV shows about books. This may well be the future of book promotion -- or, at least, one sizeable chunk of it.
