Ethics of Advertising

Obviously a big topic, but when does an advertisement go overboard?

Is it when

• It claims something that is blatantly untrue (most advertisments avoid this)
  
  
• Phrasing something in terms that make it seem one way, but are really another (most late night or mid-day infomercials tend to practice this)
  
  
• Or something more seemingly benign, but has a tremendous impact - playing with human psychology!
  
  

Human psychology has been analyzed to death by marketers and many of the best companies leave no "thought untouched" when developing their campaigns.

Have we gone too far in our efforts to sell, sell, sell?
