The commercial I chose was an AT&T commercial basically advertising, “bigger is better” phenomenon.  This commercial starts out with a well-educated looking man asking to a group of four children, “What’s better? Bigger or smaller?”  The kids obviously chose bigger.  Then he followed his question by asking if they would rather have a bigger tree house or a smaller one.  The children went on to say they could have a disco party and a “big” flat screen TV if the tree house was bigger.  Then the narrator of the commercial concludes the ad by simply saying bigger is better and that AT&T has the largest 4G network in the nation.  The main prompt of this commercial is that AT&T does have the largest 4G network and joining it would be the best decision because bigger is better, and even the children of today’s society can realize that in different scenarios.  The audience is clearly anyone watching television.  The audience is also directed to those cellphone users looking to join the largest 4G network in the nation.  Exigence is an issue that is the purpose for the speaker to present.  In this commercial, the exigence would revolve around the fact that AT&T has the largest 4G network in the nation.  Constraints are the beliefs or attitudes the audience posses.  I feel as if there could be many constraints in this commercial.  Switching to a different network can be expensive and is also a commitment.  Though if you want to be a part of a network with the highest speed access to the Internet through your mobile device, AT&T can provide that for you.  Having children display the “bigger is better” phenomenon should have the audience understanding on why being a part of the largest 4G network is better.
