The good professor is right. There is much unsupported hype about new social media taking over the role (and the audience) of traditional newspapers, radio and TV. Sure the media will change (is changing now actually) as a result of new information techs, but it’s not likely to crumble anytime soon.
Not to say that as PR professionals we should ignore social media. But for many of us, “mass media” (and not media by the masses) remain the focus of our efforts.
