Epublishers Weekly has created an interesting chart using e-book sales data from IDPF. IDPF posts a chart on their website which shows sales by quarter and Epublishers Weekly has reworked the chart to show the data on an annual basis. The annual format makes it is easy to see why 2010 will likely be a record year for e-book sales.
Note: IDPF’s figures represent the 12 to 15 trade book publishers who have been willing to supply their data to IDPF.
