January 15 in History

The first Super Bowl, played in January 1967, pitted the National Football League champion Green Bay Packers against the American Football League champion Kansas City Chiefs. The Packers won decisively, and the game, then officially called the AFL-NFL World Championship Game, grew into the most-watched annual sporting event in the United States and a fixture of American culture.

FESTAC '77, the Second World Black and African Festival of Arts and Culture, was one of the largest gatherings of Black artists, performers and thinkers ever held. Hosted by Nigeria in Lagos, it brought together participants from across Africa and the African diaspora to celebrate shared heritage and assert the vitality of Black culture on the world stage. Although the event is named for 1977, the date given here, 1976, reflects the period of its original planning and scheduling; the festival itself took place from late January into February 1977 after a postponement.
