Since Amazon announced the Kindle Singles program back in 2010, authors including Margaret Atwood, Christopher Hitchens and Jeff Jarvis have experimented with the new short form eBook format.

While Amazon is fairly tight-lipped about its sales figures, today Paidcontent.org is reporting that Amazon has sold more than two million Kindle Singles.

Paidcontent.org has the exclusive: “Amazon wouldn’t disclose its total revenues from those two million singles, but the minimum price of a Single is $0.99 and most are $1.99 (the author or publisher sets the price). So with an average price of $1.87 multiplied by two million, a rough estimate of Amazon’s 30-percent cut is $1.12 million.” (Via GalleyCat).
