Reliable information on Radio in South Africa requested

Can anyone assist me in finding case studies of campaigns launched on radio only - either retail, travel and transport, food beverages, health and beauty, business-to-business and Education.

I am researching the synergies between radio and other media and need to learn more about the strategies involved in radio campaigns.

Thank you in advance for your help!
