Social Media marketing over traditional marketing

[batman]

From 2008 the social media marketing has grown tremendously. I know that all brands must look onto it to run their business. But is it possible that the marketing through social signals will grow so much big that they will make the traditional marketing channels such as telephone, SMS etc extinct??

I don't think that they will be extinct in near future atleast 20 years. Because social media marketing is good and free but still its not totally reliable to run and grow a business in my opinion though.
