Lay's is an American potato chip brand, the company name established by 1932, and it has been a product of Pepsi since 1965.
Therefore, we can say that Xerox potato chips are brand products of Xerox, and Xerox is a subsidiary of Pepsi-Cola ~ Pepsi-Cola can only be called the leading product of Pepsi-Cola.
P.S. Actually, we are familiar with PizzaHut and KFC's Yum Global (now called Yum! ) was also separated by Pepsi at 1997.
