about advertising

When we think about advertising, likely our minds will go to TV commercials and billboards, informing some products to sell. However, behind appealing advertisements, 

there is much more to discover. 

Example of a "generic" commercial using rhetorical strategies to engage the audience but with a non-specific product to promote. 

Indeed, the Advertising industry plays a vital social role in our economy and society. Big companies and corporations invest millions in marketing campaigns to inform people about products and services and, lately, to increase awareness about social issues. So, who are advertisers? What values and goals define them? Can it be possible to draw general characteristics to depict them as a community? Where do they exchange ideas and feedback? How do they communicate?
