Surf culture includes the people, language, fashion, and lifestyle surrounding the sport of surfing. The history of surfing began with the ancient Polynesians. That initial culture directly influenced modern surfing, which began to flourish and evolve in the early 20th century, with its popularity peaking during the 1950s and 1960s. It has affected music, fashion, literature, film, art, and youth jargon in popular culture. The number of surfers throughout the world continues to increase as the culture spreads.
