The long tail is the colloquial name for a long-known feature of statistical distributions (Zipf, Power laws, Pareto distributions and/or general Lévy distributions). The feature is also known as heavy tails, power-law tails, or Pareto tails. Such distributions resemble the accompanying graph.
From the page: "In these distributions a high-frequency or high-amplitude population is followed by a low-frequency or low-amplitude population which gradually "tails off." In many cases the infrequent or low-amplitude events--the long tail, represented here by the yellow portion of the graph--can make up the majority of the graph."
