R&B remained extremely popular during the 1950s among black audiences, but the style was not considered appropriate for whites, or respectable middle-class blacks, because of its suggestive nature. Many popular R&B songs instead were performed by white musicians like Pat Boone, in a more palatable, mainstream style, and turned into pop hits. By the end of the 1950s, however, there was a wave of popular black blues-rock and country-influenced R&B performers gaining unprecedented fame among white listeners; these included Bo Diddley and Chuck Berry. Over time, producers in the R&B field gradually turned to more rock-based acts like Little Richard and Fats Domino.
