Other than radio, I believe new new new media threatens all modern day prevalent communication technologies of yesteryear. The personal computer in conjunction with the almighty internet has the ability to facilitate the transportation of any message, image, sound and text. Through social media, users are getting a more personalized bevy of information. They receive what they want to. There's less of the need for the mass message when social media has given individuals a platform on the global stage.
I'd like to say this evolution will take years perhaps a lifetime to get to the point of extinction for mainstay media technologies like radio and television. I'd like to say that because I'm hoping to have a career in either of the two, but the most amazing thing of about new new media and tech-o-lution is it's speed. It's moving pretty fast now and it only seems to be getting faster. It's impossible to predict where media will be, "When I'm Sixty-Four."
