Step-by-step explanation:
The publishing industry in the United States has undergone a significant transformation from traditional paper/print based media to electronic 'e-books.' This shift is due to the increasing popularity of digital sources and the rise of smartphones and tablets. According to a survey, the majority of U.S. adults now own smartphones or tablets, and a growing number of people, especially younger individuals, are getting their news online. This shift towards digital consumption has affected the demand for print news media, with the share of Americans getting their news from digital sources increasing over the years.
