Charlie's Angels are one of the most iconic triads in pop culture. The term 'CHARLIE's Angels' refers to a trio of female private detectives who work for the mysterious CHARLIE Townsend. The show first aired in 1976 and was an instant hit, running for five seasons. The show has since been rebooted twice, once in 2000 and again in 2019. The term 'TRIAD' is used to describe a group of three people working together, which is exactly what the Angels do.
