The Billion Dollar iPod Accessories Market
OleSurinam writes "The NYTimes has a story about the lucrative iPod accessories market." From the article: "Making add-ons for the iPod is a $1 billion business. Does that sound like hyperbole? Consider this. Last year, Apple sold 32 million iPods, or one every second. But for every $3 spent on an iPod, at least $1 is spent on an accessory, estimates Steve Baker, an analyst for the NPD Group, a research firm. That works out to three or four additional purchases per iPod."
As an employee of NPD, I can say that it's not a "guesstimate". We know the exact number of iPods sold because Apple chooses to release those exact numbers. That data comes from the only company that makes iPods. Do you have any idea how many companies make iPod accessories? There's no one source to get that information from. That's what NPD does... we're the "one source" for data across the entire marketplace.
