The commercial that has been fresh on my mind most recently is the Sprint Unlimited Data Plan commercial with the family sitting at the dinner table going around seeing how they are going to decide who gets to use all the data.  It stands out because the lighting is even dimmed to make the environment seem even more everyday-like for the viewer.  Each familiy member is heard making a seeminly-serious argument for how they should split up data usage availability- for example, the little boy says they should base it off of how much dental gear is in their mouths and then the dad says they should base it off of whoever has the least cartilage left in their knee. 

This is humorous to any member of an average family who has been in this kind of situation before, which is pretty simple and pretty much any group environment is bound to run into it at some point. This pretty much only appeals to families, because a college student or someone who pays his/her bills alone wouldn't be able to relate to the idea that it is very convenient for a family to share an unlimited data plan. 

I have seen this commercial many times on many channels at varying times of the day.  I think it is a basic commercial that Sprint knows is able to win over the minds of anyone who currently has a Sprint plan and is wanting to upgrade or who has a completely different carrier and wants to find a better one with a better deal.  Just a thought.  Appeals to the everyday person always seem to work!
