Which American fast-food chain introduced the Whopper Jr. in 1963?

Burger King introduced the Whopper Jr. in 1963.

The Whopper Jr. is the smaller counterpart to Burger King’s Whopper hamburger. The original Whopper had been introduced in 1957, and the junior-sized version gave customers a reduced-size burger using the same general flame-grilled identity.

Burger King’s menu history includes several size and topping variations, so dates are often mixed up. The Whopper itself dates to 1957, while the Whopper Jr. followed in 1963. The two products are related but are not interchangeable answers.

Burger King’s flame-grilling method is another notable part of the brand’s identity. The company’s restaurants cook burger patties on a grill, distinguishing the Whopper family from products associated with griddled or fried preparation at other chains.
