Would you like to know how much the revenue for ebooks in the US the first quarter of 2008 is?
I can tell you:
2008 Q1 – over 10 million USD.
2006 Q1 – 4 million USD
2004 Q1 – 1,8 USD
Every year from 2004, the sale has more than doubled, and there is no indication of this changing.
Now – this is something publishers should be aware of when publishing books only as paperbacks!
