When I open an app or browser on my smartphone, I'm usually focusing on a single task, where ads are intrusive and take away precious real estate from an already tiny screen. It's an enormous relief to use an app or site that just does what you want it to do and nothing more. Ironically, it's on my smartphone that I'm most likely to use an app that's completely focused on advertising. When I'm looking for a movie or nearby restaurant, I love being able to read reviews and eventually move on to a dedicated web page where I can get more info (movie times, menus, etc.). There are apps that do this very well. There are plenty of ways to get consumers to happily view advertising and promotional material, but inserting unrelated/unwanted ads into apps and websites just creates a frustrating user experience, especially on mobile.
