Network Effects Power Laws & The Long Tail Power Law – mathematical concept, frequency distribution “80/20 Rule” Power law distribution graphs tend to have long tails

Power Laws & The Long Tail

Power Law – mathematical concept, frequency distribution

“80/20 Rule”

Power law distribution graphs tend to have long tails

Network Effects Power Laws & The Long Tail The Long Tail – business strategy coined by Chris Anderson, Oct 2004 remove physical barriers, demand for niche products are actually high Ex: Amazon.com

The Long Tail – business strategy coined by Chris Anderson, Oct 2004

remove physical barriers, demand for niche products are actually high

Ex: Amazon.com

Network Effects We are moving towards a culture and economy in which the huge numbers of people who do (or can) participate in the niches of the Long Tail really matter. -- Dr. Linda Main, LIBR 246-15,SJSU-SLIS Fall 2007
