In which year did Mike Powell break Bob Beamon's long jump world record?

Michael "Mike" Anthony Powell (born November 10, 1963) is an American former track and field athlete, and the holder of the long jump world record. He is a two-time world champion in this event and two-time Olympic silver medallist.

At the 1991 World Championships in Athletics (Tokyo), Powell broke Bob Beamon's almost 23-year-old long jump world record by 5 cm (2 inches), leaping 8.95 m (29 ft 4​1⁄4 in). Powell's world record, since August 1991, still stands, making Powell the fourth person since 1900 to hold the long jump world record for over 20 years. His feat earned him the James E. Sullivan Award and BBC Overseas Sports Personality of the Year Award in 1991.
