I want to know the answer to the following question:
During what decade did hip-hop begin to be featured on the radio?
All the background I'm provided with is that "Not many disco or new wave songs were particularly successful on the AC chart during the late 1970s and early 1980s, and much of the hip-hop and harder rock music featured on CHR formats later in the decade would have been unacceptable on AC radio.". Is that enough to answer the question?
Answer: yes
