There is a huge difference between journalism and advertising. Journalism aspires to truth. Advertising is regulated for truth. I'll put the accuracy of the average ad in this country up against the average news story any time.
In advertising, sex sells. But only if you're selling sex.
The Death of Advertising? I think that's in the book of Revelation. It's the day when people everywhere become satisfied with their weight, their hair, their skin, their wardrobe, and their aroma.
Advertising is speech. It's regulated because it's often effective speech.
Advertising practitioners are interpreters. But unlike foreign language interpreters, adpeople must constantly learn new languages. They must understand the language of each new product, and speak the language of each new target audience.
Internet advertising will not replace traditional media, it will compliment them.
Advertising is totally unnecessary. Unless you hope to make money.
