Visual Rhetoric!!!

Let's start with the add's message. This add, by illustrating two old people (who are probably too old to be worrying about their kid's online behavior) is demonstrating the difficulties that many parents experience in trying to monitor their kid's online activities.  

By situating the old man on the floor, amidst a pile of remote controls, the illustrator is demonstrating the older generations inability to use even simple technology, much less a computer, thereby emphasizing the hopelessness that many parents feel.  This concept is further demonstrated by the text box above the Old Man, which says "... that's like asking cavemen to monitor the 20th century's use of the wheel!"

The old woman is holding a news paper, or magazine, the back of which reads "You Tube: Kids Access Violent Videos" which highlights one of parents key concerns about what their kids are doing, which is accessing violent content. It also illustrates the different ways in which different generations receive information.

Overall the tone of the cartoon resembles The Farside, which is another format that older people are usually familiar with and adds to the comic appeal of the cartoon.  By drawing the Parents as "old people" the author reinforces the idea that the parents inability to use technology makes them feel old.
