Amazon's Kindle Fire, a new tablet capable of handling games, has seen massive interest from customers, leading the online retailer to up production of the device.
"In the three weeks since launch, orders for electronic ink Kindles are double the previous launch," said CEO Jeff Bezos.
"And based on what we're seeing with Kindle Fire pre-orders, we're increasing capacity and building millions more than we'd already planned."
The Kindle Fire will retail at $199 along with three other versions of the e-reader.
Amazon's financial results showed a decline in free cash flow, dropping from $1.83 for the trailing twelve months ended September 30, last year, to $1.53.
