Since digital marketing and social media marketing are becoming very important nowadays, should companies forget about traditional marketing?

Hi Lana. I assume you are referring to traditional media vehicles versus the new. If that is is the case, there's little doubt that times are a-changing. Innovation is the new watchword. But that does not mean D-SM has swept the 'old' away. Any student of marketing would attest to the fact that though D-SM has added an interesting new layer to the traditional marketing mix, it does not imply that the old has become obsolete. A pragmatic marketing plan designed to succeed will never ignore the old which equals = established/known.
