The marketplace for products and services exists where consumers and product users are. At a Regional Fair, the entrepreneurs are not just presenting but often it is a destination for those who want to listen to the marketplace when things are breaking.
HYPOTHETICAL COMPANY A sells out, and new owners take over. The new owners review processes and procedures to increase efficiency and profit. They find that the starch used in making their ranch dressing product is very costly and seems almost identical to one offered by another company for a lot less money. The formula is so similar only a minimal difference appears on the ingredient statement, and it is not even the first ingredient. They changed to the other product and used it to make their companies well known for ranch dressing.
HYPOTHETICAL COMPANY B has been buying and using the ranch dressing made by company A for years, and since company B is a distributor, they have many customers who buy it from them.
HYPOTHETICAL COMPANY C buys the ranch dressing from company B. They have several local restaurants and a booth at the Regional Fair this year. They have used this same ranch dressing for years, making their Avocado-Ranch Chicken Wraps famous. They also use the sauce in their Slow-Cooker Buffalo Chicken Dip, which is not as renowned as the Ranch Chicken Wraps but is very popular. Both menu items are used in their Fair booth and their local restaurant. One of their signature sandwiches has ranch dressing as a critical ingredient.
