The Long Tail - EconReads

How the internet made it profitable to sell huge numbers of niche products, and whether the long tail has lived up to its promise for creators.

In 2004, Chris Anderson, then editor of Wired magazine, described the long tail. He argued that the internet would shift culture and commerce away from a small number of hits toward a vast number of niche products.

The idea

In physical shops, shelf space is limited, so stores stock mainly popular items: the hits. Online, the cost of offering one more book, song or film is almost zero. So retailers can offer millions of items, including niche products that sell only a few copies each. Together, these many niche products, the long tail of the sales distribution, could add up to a large market.

Evidence

Online retailers like Amazon and streaming services offer vastly larger catalogues than physical stores.
Research by Erik Brynjolfsson, Yu Jeffrey Hu and Michael Smith found that a significant share of online book sales came from titles not available in typical physical bookstores.

But hits still dominate

Later research found that hits remain enormously important:

In music streaming, a small share of songs accounts for most streams.
Anita Elberse of Harvard Business School argued in her book Blockbusters that digital markets can make hits even more dominant, as recommendation algorithms and social media amplify popular content.

Why both can be true

The long tail exists: niche products are available and many find buyers. But demand remains concentrated, and most niche products earn little. For platforms, the long tail is valuable because it attracts customers seeking variety. For individual niche creators, earnings are often small.

Finding an obscure book

A reader searches for a book on the history of braille in India. No local bookshop stocks it, but an online retailer lists it, and the reader buys a copy within minutes. For the reader, the long tail is valuable. For the author, sales may still be modest, since few people search for such a specialised topic.

Accessibility

The long tail helps readers and listeners with specialised needs, including blind people seeking accessible formats and niche audio content that physical shops would never stock.

Thinking the internet ended the dominance of hits

The internet made niche products available, but hits still capture most sales and attention. Both the long tail and blockbuster effects exist together.

Key takeaways

Chris Anderson described the long tail in 2004.
Online shops can offer huge catalogues because extra items cost little to list.
Many niche products find buyers, but hits still dominate sales.
The long tail benefits platforms and specialised audiences more than most niche creators.
