Swinging London
"Swinging London" was defined by Time magazine in its issue of 15 April 1966, and celebrated in the name of the pirate radio station, Swinging Radio England, that began shortly afterward. However, "swinging" in the sense of hip or fashionable, had been used since the early 1960s. In 1965, Diana Vreeland, editor of  Vogue magazine, said "London is the most swinging city in the world at the moment".
