How hip hop changed the world

During the summer holidays I watched a documentary on tele called how hip hop changed the world on channel 4. It basically told me that hip hop started in America in a place called the Bronx in the 1970’s. It also goes through thing s that link into hip hop like graffiti which has been used in marketing products and even just recently in the form of the London Olympics logo it is in its self graffiti. It was chosen to bring the younger generation in. Also with the Olympic official torch rally single being sung by one of the Biggest British Hip hop rap artist Tinchy Stryder. It talks about how hip hop over years has dominated the way in which we think dress and even do things nowadays.
The bit that interested me was when it talked about how hip hop originated in America but the British have bought it over here and put their own twist on it and then have taken it back over to America and Americans have done the same. It’s only been recently that we have had our own culture and stopped imitating the Americans but we can now say we have our own style this is partly to do with the N-dubz, Tinchy Stryder, Tinie Tempa and Chipmunk.
It then goes on how dance gets involved with hip hop and it actual started in London Covent garden’s where kids would go after school with their radios or whatever and start dancing and having dance off’s. Which then leads into street dance and groups like diversity and flawless.
