When this was published it was a seminal book that defined the new business model for the internet. Since then, things have moved on, and some of the subjected predicted in the book never did come to pass.In essence, the long Tail is the niche products and services that large stores and business cannot justify holding, when they only sell one or two a year. A small business could offer this prior to the internet coming along, but it was primarily mail order, or very specialised.Along come the internet, and suddenly your customers could find you far easier than ever before, and you could justify stocking the item that sold one a month. With the advent of digital products, the sales capacity is infinite.It is very well written, and i really enjoyed reading it.
