Mobile advertising is now the fastest marketing category
Because of the rising penetration of smartphones globally, mobile ads should expand at a 50% rate from 2013 through 2016. That might be good news for those who make a living in the process of producing them, or selling the mobile space they land on. But the average smartphone user doesn't appreciate his phone becoming a billboard.
The fastest growing part of the mobile ad category is in-app ads. These ads contributed $3.5 billion to the amount of money spent on mobile advertising last year, and is forecast to total $17 billion by 2018 by research firm StartApp. You better get used to seeing mobile ads on your smartphone's display, because more are on the way.
