Advertising and Visual Rhetoric
But the best servers of visual information (or at least the most creative) are advertisers.
There's a lot to learn about rhetoric by examining how advertisers are manipulating purchasers to buy a myriad of products we may or may not need. Recently, this ad found its way to my mailbox with the caption, "Can you guess the product before the end of the commercial?"
At first I thought it was some weird take on a new HGTV home redecorating show, but since YouTube so graciously provides the product in the header it's a bit of a giveaway.
Marketers know that when the audience feels familiar with something, like The Exorcist, they will feel at ease (a bit counter intuitive in this case), while the humor makes the message stick. Dirt Devil, the most powerful vacuum EVER!
But at the end of day, it's all about sales. So when looking at the details of this TV commercial, details like setting, characters, dress, and social roles, who is going to buy this product?
