Daily double

Introduced in 1931 at Connaught Park Racetrack near Ottawa by owner Léo Dandurand,[4][5] it was noted as being "a fad in England this season.

[16] In 1973, American actor and comedian Alan Carney died of a heart attack from the excitement of winning a daily double at Hollywood Park Racetrack in California.

[20] American sportscaster Clem McCarthy opined that "few players of races can tolerate such slow action for their money.

"[21] Notwithstanding, Santa Anita Park in California introduced daily triple wagering in October 1986.

[25] These wagers were typically offered only a few times on each program, largely because of the limitations of electro-mechanical totalisator systems.

The higher payouts for these wagers tended to diminish interest in the daily double, but it is still offered, sometimes more than once during a program.
