The Kindle effect? Has the Kindle effected US e-book sales?

US Trade Wholesale Electronic Book Sales

Whilst tracking Kindle sales is like guess work, tracking US e-book sales is a bit easier, the above graphic shows US e-book sales from Q1 2002 – Q1 2008. Whilst there was a healthy upward trend, the last 5 quarters (Q4 2006 – Q4 2007) only showed a 17% increase in sales according to industry statistics compiled by The International Digital Publishing Forum. However just in the last quarter alone, the industry saw an explosion, up from $1,887,900 in sales in Q4 2007 shooting up 23% to $2,460,343 in sales in Q1 2008.

I think the most interesting results will be Q2 2008, if we see another 20% spike in sales like we saw in Q1 2008 then it’s quite reasonable to theorise that the Kindle is having an effect on e-book sales in the US.

Bear in mind that The International Digital Publishing Forum only collects data from 12-15 trade publishers and that the real retail numbers could be as much as double the figures reported above.

A commenter, rizchamps, from the Silicon Ally Insider article on the report writes:

So if we ascribe all the incremental revenue from $2.5M to $3.1M = $600K to Kindle, and assume that $3 a piece wholesale cost, that would be 200K ebooks currently in service. In addition, assume that those with kindles are early adopters who would buy more than 1 book, say 10 book per kindle for the three months period, that would put the active kindle number around 20K.

Then, those 20K in service probably was mostly sold during Xmas season, give it 15K, meaning for an average month, there are 5K kindles entering service (summer time could be less because Kindle has not proven itself on the beach yet). That would translate into annual sales of 70K units(generic), give it a multiple YOY 30%, that would be 80K.

That would mean 90k (units)* (500 (price) + 50 (book per year, since adopters love books)* 10 (price per book) = $90M gross revenue

rizchamps numbers seem well worked and seem entirely reasonable, more so than a certain Citigroup analyst.

Of course all this is still guesswork and we wont know for sure unless Amazon releases Kindle sales figures. Do you think the Kindle is having an effect on e-book sales?
