When Dan Brown’s "The Lost Symbol" was released on Sept. 15, Amazon’s rankings revealed that Kindle sales outstripped sales of the hardcover. This led some ebook enthusiasts to herald the dawning of a new era. FastCompany asked, "Could Dan Brown’s new book be heralding the e-book age?" CNet wrote: "The possibility that the Kindle version of ‘The Lost Symbol’ — which follows Brown’s wildly popular ‘Da Vinci Code’ and ‘Angels & Demons’ — is outselling hard copies on Amazon could be a monumental moment in the e-book industry."
