How Long

I made a chart showing how long it would take, at current growth rates1, for Apple to sell an iPhone to every man, woman, and child on the planet:

Per Wikipedia’s estimate of world population (about 7 billion), it would take about five years.

(Uses information from the post “iPad versus iPhone versus iPod” from AAPLinvestors. PDF file here, table data as PDF here.)


1. Using HUUUUUGE amounts of approximations and simplifications, I know. Assumes projected growth rate of 20%, which from the data for the past several years, seems like a decent assumption.
