IDTechEx: the e-reader market will grow to 70-90 million units by 2017
IDTechEx published an interesting post in which they forecast that the e-reader market will grow from 30 million units in 2011 (about $750 million in revenue) to 70-90 million units (or $1.7 billion to $2.2 billion) in 2017. IDTechEx says that 70 million units will come from the leisure reading market mostly. If the education and business market takes off, it may mean another 20 million units per year in 2017.
IDTechEx says that text books for schools could be a very large opportunity - and may even double the sales of leisure reading. This isn't taken into account in the optimistic scenario. IDTechEx also expects new display technologies such as Liquavista's (now Samsung) Electrowetting technology and Qualcomm's Mirasol to enter the market soon.
