[1] In 1932, salesman Herman Lay opened a snack food operation in Nashville, Tennessee.

Lay crisscrossed the southern United States, selling the product from the trunk of his car.

Shortly thereafter, Lay's introduced what became its best-known slogan: "betcha can't eat just one".

Annual revenues for Frito-Lay exceeded $180 million by 1965, when the company had more than 8,000 employees and 46 manufacturing plants.

Shortly thereafter, the company introduced the "Wavy Lay's" products to grocery shelves, with a national rollout in 1994.

[9] Frito-Lay primarily uses the brand name "Lay's" in the United States, and uses other brand names in some other countries, including Walkers (UK and Ireland); Smith's (Australia); Chipsy (Egypt and the West Balkans[10]); Tapuchips (Israel);[11] Margarita (Colombia); and Sabritas (Mexico).

Wavy Lay's are identical to the regular brand, except for a half-gram less of saturated fat in some combinations.
