To get people to switch to the new LG G3, M&C Saatchi Stockholm created some targeted Smartbanner ads on iPhone and HTCs. These mobile banner ads call out their battery performance, attempting to convince them to switch G3, because it has better battery performance.
These ads appeared when people were using in-flight wifi via Norwegian Air long haul flights.
Neat idea. But it's also why I'm adding more and more ad blockers and do not track search engines.
