mjasay writes "Remember 'the long tail?' That was the idea that there was gobs of money to be made in the more obscure tastes of any given market, enabled by the web. In recent research highlighted in the Harvard Business Review, however, the long tail theory comes under withering criticism. Not only is a hits-based business more profitable for vendors according to the new research, but the research suggests that consumers also derive more enjoyment from the hits, rather than the tail. In short, the researchers find that 'the tail is long and flat, and therefore that content providers will find it hard to profit much from it.'" Long Tail advocate Chris Anderson defends his theory, and it seems that most of the debate centers around how you define "head" and "tail."

Doubts Multiply About the "Long Tail" 194 comments
fruey sends in a New Scientist analysis of the many second thoughts about the Long Tail theory. It summarizes four studies that show, in different markets, that the tail is both flatter and thinner than originally supposed, and that blockbusters are not going away in those markets — they are getting bigger. It's theorized that widely used collaborative filtering software is magnifying the winners' share of the various pies, and peer influence is a large contributor to consumer behavior.

why are they concentrating on how *profitable* the long tail is?
As far as I see it, the long tail isn't about PROFIT, but about how much society wants the entertainment.
How many REALLY old songs would you like to hear again? Well, given that each year older adds another pile of songs, the profit in EACH TITLE is spread thinner and thinner. Because what I'd like to hear again from the 70's isn't what YOU'D like to hear from the 70's.
The long tail is showing that copyright lengths ARE damaging society. And it not being profitable enough to make a business on shows that there is NO BUSINESS LOSS in shortening copyright to a time where works are still wanted.
Really, copyright now is more about the accountants' abject fear that someone else is making money and not them.
Shit, if you're not SELLING a good, why not let someone else do it, or even just release it for free and forget about it? Because in that case, there's no money for you to make. That you don't want to spend the effort to MAKE the money in the first place seems irrelevant to your accounting brain.
So I don't understand the ribbing. It's arguing that it isn't profitable when that's not what the long tail is about. It's about demand continuing BEYOND the profitable age of entertainment goods.

Redbox explained (Score:5, Interesting)
Redbox is a vending-machine movie rental system. I walk into the Wal-Mart a mile from my house, and there's this big, well, red box sitting there. It operates on the opposite of the "long tail": it only has a couple dozen of the very latest movies, has many (but not infinite) copies of each, costs $1 per night (just swipe your credit card), keep 'em as long as you want (after a month, just keep it - for $29 you've already paid for it), rental & return is rediculously simple with none of the "video store" hassle.
Instead of having everything anyone might be looking for (the "long tail" model), it has a few things that most people will probably want (say, the "dirt cheap blockbuster" model). Turnover of content is very high, so there is most likely something sufficiently interesting (for a buck a night, that's a lot) there at any time. Content range is very narrow, so customers can browse very quickly; covers of most movies available are shown on the front of the vending machine, so one can review what's available in just a few seconds (a thourough list is available by touchscreen) even while someone else is actually using the machine. And with rentals being just a buck a night, getting something or keeping something a few days is trivially cheap.
It complements Netflix/Amazon thus: instead of getting exactly what I want in a few days, I get something satisfactory right now. My "long tail" providers can find anything I specifically want within a few days, but if I simply want a couple hours' entertainment now I can get something suitable, dirt cheap, in a few minutes. And when I take a rental back, it's just too easy to pick up another. It also fills the gap between "long tail" services and TV's "you'll watch what we want when we want" model.
That the box is located at the entrance to a store which thousands of people frequent with great regularity, rather than being a special trip, completes the winning business model.

I can see where low volume stuff isn't worth the hassle.
The whole premise of the Long Tail idea is that it's NOT a hassle for internet companies like Amazon and Apple to keep the low-volume stuff in inventory. That's what gives them an advantage over brick and mortar. If Amazon only sells 5 copies of the The "Long Tail: Why the Future of Business is Selling Less of More" a year, it only needs to keep 5 in inventory. If a chain store wants to sell the book it has to keep hundreds in inventory to ensure they have at least one in each store.
A lot of people mis-characterize the Long Tail as "making money by selling obscure stuff." That's only half of the definition. The other half is building a business where it does not cost you anything to keep lots and lots of obscure things in inventory, or alternatively, having access to millions and millions of customers, so if you sell to 1% of your market, it still adds up to something. Long tail does not work unless all of those 1% niches add up to 80% of the total market or unless you sell to 1% of a billion people. The internet helps businesses do both of these things.

A specialty store would focus on a wider selection of a particular type of good. So the cheese shop might have 50 varieties, and the plumbing supply place will have 50,000 plumbing parts in stock. The margins here are high, because the customer needs a particular type of a hard-to-get item.
Amazon and iTunes have a business model that scales out enough that they can pay the bills by selling high-volume, low-margin items while making a profit on low-volume high. When you build a giant, automated warehouse in the middle of nowhere, the marginal cost of storing one more book is very low.
Killing the slow-moving stock would kill Amazon, because that's where they make money!
On the other hand, carrying high-volume, low-margin items in a speciality retailer can kill the business. If a high-end steakhouse started selling $3 roast beef sandwiches, their customers would either leave, get crowded out by people buying sandwiches or stop buying $50 steaks.

Correct me if I am wrong, but the basic gist I got was that the 'long tail' theory states there is a lot of money to be made in 'niche' or 'subculture' elements, and the critics say this is wrong. I can wholeheartedly disagree. It's not easy to extract the profit from niche markets, and the long tail probably doesn't add up to the 'head' so to speak, in most cases, but there is certainly a lot of money to be made.
Take TV for instance. Your 'Heads' there may be ABC, CBS, NBC, and you could call things like The Discovery Channel, The History Channel, Comedy Central, Sci-Fi Network, etc the 'tail', as I understand it.

It's not the shape, the shape is fixed...
It's a standard power curve... it agrees that the hits make up lots of the sales, the thing is how many.
Integrate from 1 - 10 off the curve, you see the sales of the Top 10 sellers... they sell a lot, they sit in the front of book stores. Go to 1-100, and you have probably only doubled sales.
Long tail observes that theoretically, the curve goes out to infinity and never hits zero, which is what the Internet makes interesting.
A mall book store can stock 5000 books, a big box book store 20000, and Wal-mart's book section, 1000. Wal-mart moves a lot of books because they stock the 1000 most popular books and move them readily. The mall book store have 5x the inventory and probably about the same in sales, because they aren't moving as many of the top 1000 because of Wal-mart. The Big box store, with 15000 moves more... maybe double the mall bookstore with 4x the inventory?
You see diminishing returns... so sales people observe the 80/20 rule, 80% of your sales come from 20% of your customers/products, etc., it's the power curve... But long tail observes that if you can only carry 100 products, 80% will come from your top 20%, but if you carried infinite inventory, the long tail exceeds the bulbous head because it's infinite.
The average bookstore apparently stocks around 15k books (when I first read the long tail argument), the most profitable books. If you looked at Amazon's sales, their "big sellers" were the sale 15k books as everyone else, so you would think 80/20 rule, that's 80% of revenue, the other 1M+ books were just there because they were slightly profitable, brought customers in, etc. Turns out, the majority of the sales were from the books AFTER rank 15K, the books that booksellers don't carry.
This brings one to two conclusions:
1. 80/20 rule is a function of limited inventory, if you take the tail to its conclusion, the tipping point is around where others drop off, with half before and half after, so the bulbous head is 80% of 50% of sales, or 40%... still important, but not the final say in revenue... Long tail means Internet changes the economics of inventory... I go to a Wal-mart OR Website for my "common" stuff, Internet for everything else.
2. Amazon.com does well on the long tail because the others can't play there. The normal shops compete for the first 15k, Amazon has a competitive advantage for the rest of the inventory, and therefore makes profits. -- This leads to the natural conclusion that the long tong tail is a natural monopoly, only one player can make money stocking it. Wal-mart owns the common 20% of items, Amazon sells the rest, and we all get out of retail because Retail = Wal-mart + Amazon.com.

I haven't read the book, but your explanation is how I understand the theory.
In the case of Amazon, I think your second conclusion, that Amazon does well on the long tail because they're the only ones there, is what is actually happening.
I buy a lot of esoteric testing, stats, and linguistics texts. That, in fact, is all I buy, and I buy a lot of them. And Amazon is the only place that carries them.
Same thing goes for CDs. If I want, say, the new NIN (ignoring for the time being that the last couple NIN releases I've actually gotten from his website), I go down to Tower Records (still alive here in Japan). If I want Freezepop, I need to go to Amazon.
Actually, in both of these cases, as long as I'm going to Amazon for the relatively unpopular thing, I might as well pick up the popular thing there while I'm at it.
I guess what I'm saying is that I don't think the long tail is necessarily a model for everyone, because if everyone did it, they'd see no returns. But for any particular market, a single long-tail retailer can make a bundle. Everyone jumps in and everyone loses money. It's a function of how big you are, not what you carry. Amazon basically has no competition on the "long tail" products, so they get 100% of that business. They have the luxury of doing that because they are frickin' huge.
So, all told, it just doesn't seem to me that the long tail is something just anyone can use, which is pretty much exactly what the study found.

The problem with the "long tail" is that companies assumed it scaled. By definition it will only apply to a fringe. There is only space in such fringe areas for one or two dominant players; these players may make gobs of cash, but only in relation to their market size.
Of course large vendors aren't going to find it profitable to appeal to multiple fringe markets. The level of effort involved to support each individual small market is high and then combined with a number of markets means you end up burning through more manpower per dollar than a smaller dedicated company. It's the same problem of having too many products/SKUs/whatever, see DEC/Apple pre Jobs for an example of failing this way.

For a brick and mortar store, concentrating on the sure hits makes a lot of sense. Funny story, my dad had to pick up a new alternator for a 30-year old truck. The local parts store had one in stock. The parts man looks the box over and says "Yep, had this one on the shelf for about 18 years." That's a bit longer on turnover than most businesses would shoot for. But when you're talking about cheap warehouses in the bad part of town doing all of their selling and shipping online... this whole argument could probably be solved with access to Netflix's database and a few queries. My hypothesis:
1. A huge percentage (35%?) of their business will be new releases.
2. The next biggest percentage would fall into the "perennial classics" category, i.e. the kind of movies that aren't new releases that a Blockbuster would have, movies that do a steady, dependable business.
3. Everything else would fall into the "obscure shit" category, the stuff that Blockbuster does not carry because it's too infrequently rented.
I will wager that the revenue from #3 more than pays for itself AND serves as a draw for customers who rent across all three categories. Joe Customer chose Netflix because they carry obscure Asian chop-chop flicks but will also rent Cloverfield from them since hey, he has an account.
As another example, say I want to pick up some obscure, out of print book. I hit Amazon first out of force of habit. Good news, they have it. That makes it all the more likely for me to type in Amazon when I want to buy the next top-seller I saw on the Daily Show. If Amazon didn't have the obscure books I want, I might go to some other site by default, and then they'll be getting all of my New York Times Bestseller business.
If we're talking about a brick and mortar store, the carrying cost of the truly obscure could well be too high to justify itself. With online stores, there's no excuse not to carry the obscure.

Amazon makes the long tail work because Amazon is still a big fat book store (and sells other things): books have a shelf life measured in years. Books do not decay, they do not fall out of fashion, they do not get replaced by next year's model (mostly). As such, Amazon can build up a long tail of obscure books and build a brand of a bookstore where you can find anything.
Zappos is trying this with shoes. The problem here is that Shoes fall out of fashion, so I am not sure that works. I used to work for a company that sold outdoor gear-- it kinda worked as some things were durable, but even then most equipment (and especially apparel) have a shelf-life of one season (one year).
Music may work-- someone's always searching for some Captain Beefheart or TSOL-- but certainly the biggest profit (because production costs are so low for massed produced copies) are in the big-hit ranges.

As Anderson notes, the defintion of "head" and "tail" are important; Anderson was initially basing his information off of the result of switching away from retail space. If less than 1% of the items of a market can make it into the inventory of a Wal-Mart, then even if the top 1% is 32% of sales, the Long Tail is pretty powerful.
Around the "research suggests that consumers also derive more enjoyment from the hits, rather than the tail." From the article -
Popularity and quality are not completely divorced from one another; I'd expect the more popular titles to better, just not nearly to the same extent as their sales would indicate.
I'd be interested in "in-genre vs out-of-genre" ratings for the heavy users as well; while the article indicates that heavy users rate popular titles disproportionately highly, this may be a result of the heavy users (who consume a lot of obscure stuff) working primarily within their genre as opposed to across genres. If you like action movies more than romantic comedies, you're more likely to give the action movie the higher rating if you both of them and they're of equal quality. I think it's likely (though not certain) that heavier consumers stick more to their genre/tastes even among the popular items, which would result in them having a disproportionately high rating for popular stuff compared to lighter consumers. (The article does note the disparity is true for products as a whole - heavier/obscure consumers are more likely to stick to a single genre - but doesn't run the comparison among the popular subset of their tastes).
As for the business suggestions, some of them seem ok, but others -
There's a difference between knowing something isn't actually any good and the amount you'd pay for it, especially for obscure products. Consumer ratings are not directly analogous to the price premium someone would willingly pay for something, and not simply in the people buying things because they suck market; things like completionism and other impulses that aren't connected to a work's quality will lead to obscure works being worth high price premiums regardless of quality.
While you shouldn't radically alter things, this is ignoring the issue of what the "head" is in the first place. If the "head" of an online store is bigger than the entirely inventory of a typical Wal-Mart, there's going to be a shift in marketing tactics.

It doesn't mean the end of blockbusters, because people LIKE blockbusters. It means that you have more alternatives, so you can see something else, but in general, you won't. Most people like what most people like. Duh. The additional cash that goes to the "long tail" artists does make them a bit less profitable, but there's still plenty of profit in them.
So the Long Tail doesn't mean that your rock band is going to be as rich as Van Halen. It means that you can make a few hundred bucks, but it's not going to make you a living, much less a superstar.
