Print Ads Have High Retention Rates

Magazine and newspaper ads can be viewed in a single glance and don't require scrolling or clicking through. When people read offline, they tend to have longer attention spans. Web reading is useful for gathering quick blurbs of information, but people pay more attention to what they are reading in print. For this reason, consumers tend to remember more of what they read (and see) in print.

Print readers are also very loyal readers. People who read magazines or newspapers do so regularly. This loyalty, combined with the high retention rates, make print a very important medium for branding.
