NEW YORK (AP) — Over his career, former heavyweight champion Mike Tyson recorded 50 wins and six losses. Cameras captured Iron Mike as he learned about the contest, located a bird to enter — he dubbed the tiny guy "Little Mike" — but then suffered a TKO when a competing champion cheeped and peeped more than his bird did in the same 15-minute period. The series, kicking off on Sunday with Tyson's episode, mixes travel adventure, history and journalism to shine a light on global stories. Back home, Tyson is watching his former profession lose out to professional mixed martial arts but thinks he may have the answer to put the "sweet science" back on top: A compelling boxer somehow unifies the heavyweight title.
