Do you have a pitch deck you can show me?

What?

The “long tail” refers to niche areas with only a few people who want something in a market. It’s talking about the graph of a distribution of potential consumers for something.

Like, there’s normally a lot of people interested in a few things. You can sell a blockbuster to them. But then there’s this long tail of people interested in small, niche areas. If you can bring more of them together or reduce production costs, it starts to be viable to make things for them as well. The Internet is often described as bringing people with those niche interests together, so that people on that long tail become numerous enough to make something for. Bringing down production costs has the same sort of effect.

In business, the term long tail is applied to rank-size distributions or rank-frequency distributions (primarily of popularity), which often form power laws and are thus long-tailed distributions in the statistical sense. This is used to describe the retailing strategy of selling many unique items with relatively small quantities sold of each (the “long tail”)—usually in addition to selling fewer popular items in large quantities (the “head”).

The long tail was popularized by Chris Anderson in an October 2004 Wired magazine article, in which he mentioned Amazon.com, Apple and Yahoo! as examples of businesses applying this strategy.[7][9] Anderson elaborated the concept in his book The Long Tail: Why the Future of Business Is Selling Less of More.

Anderson cites research published in 2003 by Erik Brynjolfsson, Yu (Jeffrey) Hu, and Michael D. Smith, who first used a log-linear curve on an XY graph to describe the relationship between Amazon.com sales and sales ranking. They showed that the primary value of the internet to consumers comes from releasing new sources of value by providing access to products in the long tail.[10]

Before a long tail works, only the most popular products are generally offered. When the cost of inventory storage and distribution fall, a wide range of products become available. This can, in turn, have the effect of reducing demand for the most popular products.

Some of the most successful Internet businesses have used the long tail as part of their business strategy. Examples include eBay (auctions), Yahoo! and Google (web search), Amazon (retail), and iTunes Store (music and podcasts), amongst the major companies, along with smaller Internet companies like Audible (audio books) and LoveFilm (video rental). These purely digital retailers also have almost no marginal cost, which is benefiting the online services, unlike physical retailers that have fixed limits on their products. The internet can still sell physical goods, but at an unlimited selection and with reviews and recommendations.[31] The internet has opened up larger territories to sell and provide its products without being confined to just the “local Markets” such as physical retailers like Target or even Walmart. With the digital and hybrid retailers there is no longer a perimeter on market demands.[32]

You have to have at least a certain number of potential sales before it becomes worthwhile for a human to address a niche. If the cost falls, then new niches become viable to sell to. So now you can make, say, R&B aimed specifically at teenage female Inuits or something.
