As a fan of both Freakonomics and The Undercover Economist I'm convinced I need to read an upcoming title called Why Popcorn Costs So Much at the Movies. I enjoy these books that talk about hidden trends in the economy and everyday products.
The author, Richard McKenzie, also created a video trailer for the book which I've embedded below. I'm seeing more and more authors and publishers investing in promotional videos for their books. This one is pretty simple but it's extremely effective; now that I've watched it I feel like I know more about the author and his book than if I would have simply read through a book description on Amazon, for example.
I plan to read Why Popcorn Costs So Much at the Movies and will post a follow-up review when I'm finished.
