"But what has captured publishers’ attention is the increase in the number of people reading their phones. In a Nielsen survey of 2,000 people this past December, about 54% of e-book buyers said they used smartphones to read their books at least some of the time. That’s up from 24% in 2012, according to a separate study commissioned by Nielsen. The number of people who read primarily on phones has risen to 14% in the first quarter of 2015 from 9% in 2012.
