In 1970, Nissin formed the subsidiary Nissin Foods (USA) Co. Inc, to sell instant noodles in the United States. Nissin recognized that the bowls traditionally used to package instant noodles in Asia were not common in the U.S, so they used the paper cup designed by Ron R. Matteson. In 1971, they introduced instant ramen packaged in a foam cup. The three original Cup O ' Noodles flavors in the US were beef, chicken and shrimp. Pork flavor was added in 1976. In 1978, Nissin Foods offered more new varieties of Top Ramen and Cup O ' Noodles. The product was known as Cup O ' Noodles in the United States until 1993.
