Advertisement Campaigns are based on Returns on Investments not on accuracy. For example, lets say a "Pet Insurance" company makes on average $400 profit for each customer they obtain. It makes sense for them to spend $200 to acquire each new customer. You could send out around 300 bulk letters for $200.

Obviously some of those people only bought a $4 gold fish and will laugh at the pet insurance quote.
