Ad blocking on cell phones is rare, whereas ad blocking on desktop computers continues to grow. Why? Because desktop websites that have advertising have way too many ads on 1 page. Even worse are the websites that have video ads automatically play, which slow down some computers. Hopefully publishers pay attention to this when deciding how many ads to cram into their mobile websites. The future of banner ads depends on publishers not getting too greedy with having too many ads on the same page.
