We're pretty sure your grandson will never be a paperboy. Probably because by then newspapers in their printed form will no longer exist.According to a Pew Research Center poll, the number of Americans reading print newspapers, magazines and books is in rapid decline. Over the last decade, the percentage of Americans who say they regularly read a print newspaper has dropped from 41 percent to a new low of 23 percent. However, the same poll shows Americans enjoy reading as much as ever – 51 percent say they enjoy reading a lot. This is little changed over the past two decades, but most of us are shifting to digital platforms to read the papers and books. Substantial percentages of the regular readers of leading newspapers now read them digitally. Currently, 55 percent of regular New York Times readers say they read the paper mostly on a computer or mobile device, as do 48 percent of regular USA Today and 44 percent of Wall Street Journal readers.
