The long tail refers to the phenomenon in which a large number of niche products or services collectively make up a significant portion of sales or demand, rather than a small number of popular items dominating the market. This concept was popularized by Chris Anderson in his book “The Long Tail: Why the Future of Business is Selling Less of More.” The long tail is often seen in online markets, where the vast selection of products allows for a wider range of consumer preferences to be met. This term highlights the shift from traditional “hit-driven” business models to a more diverse and personalized approach, where the cumulative sales of less popular items can rival or even surpass those of the top sellers. In essence, the long tail represents the power of choice and the potential for success in catering to niche markets.
