Rock and Roll came from a fusion of musical cultures, and in turn its influence fed back to these cultures, a process of borrowings, influences that continues to develop rock music. Rock 'n' Roll had runaway success in the U.S. and brought rhythm and blues-influenced music to an international audience. Its success led to a dilution of the meaning of the term "rock and roll", as promoters were quick to attach the label to other commercial pop.
Rock 'n' Roll started off in the early-to-mid 1950s in the United States of America. African-American artists such as Chuck Berry, Little Richard, Bo Diddley and Fats Domino played predominantly to African American crowds. While these key early rockers were indisposed to racism, local authorities and dance halls were very much divided upon racial lines.
Mainstream acceptance of rock and roll came in the mid-1950s when what Bo Diddley describes as 'ofay dudes' (or Caucasians) signed to major labels and started covering their material. Elvis Presley and Bill Haley and the Comets, Buddy Holly, Ritchie Valens, The Big Bopper, Jerry Lee Lewis and Johnny Cash often toured and played together in dance halls and clubs across the US and Britain.
