The Long Tail Theory is a term that was coined by Chris Anderson in the year 2006 that has gained popularity in the last few years. It is a retailing concept describing the strategy that retailers use, this is the niche strategy, retailers sell a large number of unique items in small quantities whilst also selling fewer popular items in larger quantities. The name long tail comes from the longer, flatter, low end of the market, as demonstrated by the end of the graph above. We can say the long tail theory in short is buying more of less and less of more.As an example an old game on the Sega Mega Drive can be really hard to find in any where but specialist shops but in recent years retro games such as Earthworm Jim or Golden Axe can be easily found with but a few clicks of a mouse when searching online.
