Pizza became more popular in Italy after it took off in the US

Pizza was invented in Naples, though it wasn't particularly popular outside the region.

It's something anthropologist Agehananda Bharati calls "the pizza effect."

Hibachi restaurants were designed to appeal to American soldiers stationed in Japan

Hibachi-style cooking was originally used in residences, with Japanese families cooking together around the grill.

Despite the differences between teppanyaki and hibachi, diners began using "hibachi" to describe the concept. Later, the Aoki family brought it to American soil with Benihana.
