Punks, Ravers, Mods and Teddy Boys. No, these aren't some hot new bands, but the names of a number of British youth subcultures(亚文化) from the last 70 years.

Youth Club, a UK not-for-profit organization, released a book earlier this year celebrating many different subcultures from throughout Britain s recent history.

"A catalyst(催化剂) for creativity on the worldwide stage, British youth culture movements from the Teddy Boys of the 1950s to the grime Scene of the 2000s continue to play a pioneering role in music, fashion and creativity across the globe," it wrote on its website.

These subcultures were traditionally a way for young people to show their personalities to others. Walking around London in the 1970s would have meant seeing dozens of young "punks" - people dressed in ripped denim(破洞牛仔裤), leather jackets, body piercings(穿孔) and with brightly-dyed hair—on the streets. And in the90s, “ravers” were young people who threw all-night parties in abandoned buildings or car parks.

So, what was the reason behind these subcultures?

"On both sides of the Atlantic, more and more young disappointed teenagers were looking for an escape from the boredom and constraints(约束)of society, "wrote lan Youngs, BBC entertainment reporter. "Unemployment, racial tensions and social upheaval (剧变)added fuel to their fires."

Youth subcultures have all but disappeared in the West. Some experts believe the reason for this is the instant and low-priced availability of music and clothing in the internet age.

"Fashion and music, they’re much cheaper and they’re much faster today, " Ruth Adams, a culture lecturer at Kings College London told The Guardian.

"When I was a teenager, you had to stick to one type of music or fashion, because it cost more money. Now, it' s all a bit more blurry(模糊不清的),” she said, believing that it's harder to figure out someone's personality or music tastes nowadays just by looking at them.

Despite this, Adams believes that today’s young people are still finding their own way to express themselves, but in a more modern way.

"It's certainly happening online," she said. "It's a lot easier to use personas(伪装) online just by showcasing certain types of mysterious knowledge."
