One reaction which was not surprising was, because it would be terrible. However, that isn't answer at all, that is a statement about what the world might be. My question is more targetted. If publishers (and authors) can profit from books in ads, why don't they have them? It is all about the money.
Here were would be explanations and my response:
- Readers would not buy books: just as some people don't watch TV because of ads, of course some people would not buy books. But how many? Could it really be that most of the population is happy to see ads everywhere but a good book they will not read if they see a single ad? Add to that the cheaper price of books and this one doesn't stack up.
- Authors would not write books: of course, some authors may want to distance themselves from grubby commercial stuff. Of course, I don't know any author who refuses to let their publisher promote their books! Again, this can't apply to all authors. Indeed, if ads were to make my textbooks cheaper, then I am all for it. Not to say that I would want to see a cigarette ad but an ad from a consulting firm as to how good an employer they are, sure.
- Readers would not look at ads: in many respects, it is always surprising to me how much people look at ads in newspapers, tv, radio etc. It is not at all clear that books are anything special. Indeed, a book with a single ad in it will have that noticed. Even where there were instances of ads in books, such as for other books by the same author or publisher, they are noticed.
- Books have small print runs: then the ad rates will be low. Ads are paid for by eyeballs. Low eyeballs means low ad revenue but it doesn't mean no ad revenue.
- Some books have (had) ads; travel guides, help books and self-promotion: these are interesting but are still small enough that my question's premise is still justified. Nonetheless, it is interesting to think about why self-promotion ads happily appear in books. By the way, they are not in the Harry Potter series but I suspect that is author intervention. But they are in lots of other children's books. Perhaps my question could be rephrased: why don't books sell ads?
- Advertisers demand glossy colour ads that it would be too costly for books to provide: this doesn't seem at all plausible a reason. First, there are many books that are colour and glossy (my Principles of Economics book for one). Second, a page of colour printing in a book will cost the same as a page in a magazine. The issue is that in one case the publisher gets the revenue to cover it and in another it does not. Third, not all ads are colour glossy. Google is the biggest ad seller in the world and they are as plain as plain can be.
- Ads are time sensitive, books are not: Let's compare this with magazines. First, I am not sure ads are all necessarily that time sensitive. All the marketers tell me is that to get brand names that are lasting is key. How could it be that a corporate image is fleeting? Remember ads are not simply to inform about current promotions but to build recognition, value of association, etc. All this might make them very suitable for books. Second, not all books are so long lived. Textbooks go out of date. Bestsellers have their limited life. And books can be reprinted to update the ads. Compare this to the magazines still sitting in waiting rooms over the world. (Also, as we move to e-books, then ads can potentially update over time but I admit that that is the future -- more on this below).
- Advertisers would not buy ads because they cannot control their impact: this suggested that there was something intrinsically uncertain about the nature of book readers that isn't shared by other media. Now it may be that because of the lack of ads in books they do not have the more sophisticated ratings data of TV, radio and newspapers but how hard would it be to build that up? Even if a book turned out to be selling to a surprise demographic, the ads could be changed in reprints.
In summary, many of these answers are explanations as to why all (or most) books do not have ads but not explanations as to why (virtually) none have them. As an economist, I like thinking at the margin. That is a powerful tool as it usually leads to a conclusion that we are not at corners. When something doesn't occur, there would be a glaringly obvious explanation. Here, I have yet to find it.
Put simply, the current state of affairs does not seem robust. One publisher of one book somewhere should be able to find a price at which they can sell one page of that book to one potential advertiser out there. That we don't even see that is the real puzzle, let alone a more ubiquitous state of affairs.
That said, I think change is coming. E-books will get around even the most salient explanations posted by blog commentators. Advertisers will be able to embed hyperlinks in the margins of e-books. They can be updated and moreover the advertisers could pay for ads viewed so there would be no issue of monitoring.
