For press releases, this is the thing that consumers dislike! This is when you create something that promotes an idea for a story. While advetising on the other hand, is a product or service you're selling and are using certain techniques towards a specifc audience that would be best fit for your product or service. An example of this is the super soaker by Lonnie G. Johnson. When he made the super soaker, the age range was around 5 - 15, this what you call a audience, which is the consumer the advertiser is trying to convice to buy their product or service they are selling.
