Printed media cannot capture the sound and movement required by an audience raised on the audio and video of television and the Internet.
Because printed media involves production, information requires a lead time before it ever reaches you. Our fast-changing world might make that knowledge obsolete by the time it appears on the page and reaches your doorstep.
At minimum, printed materials require paper, which is harvested from trees; and ink, which comes from chemicals. Both require time-consuming and expensive processes to make.
Print can only reach its audience when it is distributed through an infrastructure that requires vehicles and people, which costs money.
After you read printed media, you're left with material that you need to throw away. This waste continually accumulates in our landfills.
