From How to Shoot Video that Doesn’t Suck, Page 61:
Videos have genres, although you may not be used to thinking of them that way. Instructional videos, “punked” videos, music videos, webcam rants, sketch comedy, stop-motion animation—the definitions are still evolving, but they’re there. Video genres both communicate what your video is about and lock you into expectations. Fail to deliver on the genre expectations, and the audience is disappointed.
A sketch comedy video had better be funny. A music video needs to show the band and the entire song. A wedding video needs the “I do” moment. A product demonstration video should clearly show you why you’ll love the product. I should laugh and cry while watching a memorial video, and learn how to stack boxes during a workplace procedure video.
Genres may seem limiting, but actually the expectations they set up can be fun to screw with– Witness this mashup of a musical and college admissions video from Yale. (This Harvard Response is rude and very funny– but being straight Parody genre, it has nothing to do with mashups.)

Just waded through the "Why I Chose Yale." While it is well produced by professionals and features lot of Yale grads, it seems like a parody. It was good for some laughs at this end and made me glad I didn't have to spend four years with the insufferable elite. If you want more insight into what's wrong with elite schools read my summary of "Excellent Sheep" then buy the book. Here is the link. http://bit.ly/1EUDxrH
I just finished listening to your book. It is excellent. Thanks for doing it. I will share it with my readers soon at http://DrDougGreen.Com – My only suggestion is to make it easier to find the examples from the book at your site. Keep up the good work.
Thanks, Doug. All the examples are listed here: https://stevestockman.com/examples/, but I can see where there’s a little more searching involved with the audio version what with no obvious page numbers and all.
