These days, a lot of folks call it Super Bowl I. But technically, it wasn't.

Back in 1967, the world had never heard of such a thing.

Instead, it was kind of a grudge match.

They called it the AFL-NFL World Championship Game — the first time the top teams from two fiercely competitive football leagues had ever faced off. The Green Bay Packers, NFL champions coached by the legendary Vince Lombardi, faced the AFL champion Kansas City Chiefs at the Los Angeles Memorial Coliseum.

The name Super Bowl would not officially be used until the leagues merged a few years later.

The game was played at the Los Angeles Memorial Coliseum on January 15, 1967.
