Radio is being changed by the rise of digital communications – particularly those that are cellphone-based. Call-ins and live-reports are common, thanks to mobiles. SMS comments and polls are common. Twitter and Facebook (and Mxit in the case of Radio Grahamstown) integration allows for expanded interaction with audiences.
So, should radio itself go digital? To be sure some radio services are digital, being available to audiences live or downloaded on the Internet. But traditional dissemination via the airwaves is still analogue.
