Final answer:
The term 'Hip Hop' was coined by Keith Cowboy and popularized by DJ Afrika Bambaataa, emerging from the South Bronx and spreading worldwide through various diffusion patterns.
Step-by-step explanation:
The term Hip Hop was coined by Keith Cowboy of Grandmaster Flash and the Furious Five, and it was popularized by DJ Afrika Bambaataa. Hip-hop is said to have started in the South Bronx of New York City in the mid-1970s, emerging as a cultural movement that encompassed music, dance, and graffiti. Early figures like the Last Poets, Gil Scott Heron, and subsequently Afrika Bambaataa were pivotal in describing inner-city life and social issues through their music. The adoption of hip hop in different regions, for instance, New Jersey and Los Angeles, demonstrates the concept of stimulus diffusion, where the core idea spreads, but adaptations are made based on local preferences. The spread of hip-hop music followed patterns like contagious diffusion and hierarchical diffusion, reaching from nearby locations to more distant ones and from large cities to smaller towns respectively. Hip hop's influence is now global, with examples of its cultural impact visible in Japan and the Middle East, altering the original style to fit local narratives and conditions.
