Dive Insight: 

It was only a matter of time before the advertising world began utilizing mobile devices' location sensors to deliver more personalized experiences. In places like malls and airports, it seems like mobile users might be open to the messaging. The scope of what is possible with this platform is fun to think about, as well. Imagine more interactive trade shows and conferences, for example.
