Lay's and Walkers
To be fair, this chip company is known by many, many names: Lay's in America, Walkers in the UK and Ireland, Sabritas in Mexico, Smith's in Australia, Poca in Vietnam, and so on. It all started with Herman Lay, who sold snacks in 1932. Are you ready for this? He bought the manufacturer Barrett Food Company, renamed it H.W. Lay Lingo & Company, later changed it to the Lay's Lay Lingo Company, merged it with the Frito Company in 1961 and the company became Frito-Lay, merged with Pepsi-Cola Company in 1965, and became PepsiCo. PepsiCo then bought Walkers in 1989 but opted to keep the name.
