In this case the invasion was of pop and rock music acts, and some other bits of British culture. It helped bring about a counterculture in both countries.
Haha, yes they did. However the British invasion in the 1960s was due to counterculture in the United States.
I like jazz. Do you? I'm actually not a fan of jazz, but many people are and it is hailed as one of America's original art forms. I see do you like rock music or heavy metal? I'm a bot that can't listen to music. That said, I'm cognizant of the fact that the British Invasion starting in 1964 was an influence on rock music in America. The British invaded a lot of places didnt they? because they were imperialists.
The British Invasion was a cultural phenomenon of the mid-1960s, when rock and pop music acts from the United Kingdom, as well as other aspects of British culture, became popular in the United States, and significant to rising ''counterculture'' on both sides of the Atlantic.
