Who won the first season of 'Big Brother' (US)?

Eddie McGee won the first season of 'Big Brother' in the United States.

The season, originally titled Big Brother 2000 and later known as Big Brother 1, premiered on July 5, 2000. Ten strangers lived together under constant observation with no communication with the outside world, but the format differed sharply from the modern show. Evictions were decided largely through public voting rather than the familiar Head of Household and Power of Veto system.

The season lasted 88 days and ended with Eddie defeating Josh Souza. Eddie received 59% of the public vote in the finale, while Josh finished as runner-up with 27%. Lisa Donahue was a contestant from the second US season, and Mike Malin and Will Kirby became associated with later seasons, which makes those names plausible but incorrect choices for the first-season winner.
