I started a global branding and marketing firm 19 years ago. Marketing is a term that means different things to different people so it helps to clarify whether you are talking about market research, PR, social media, advertising, promotions, guerrilla marketing, strategy, analytics, SEO, SEM, B2B, B2C, content, etc. There are so many tools in the marketing toolkit today but I think it is redundant to say digital marketing because truly everything has a digital element since everyone is accessing and interacting with your brand online, through their phone or via the website at some point. In the old days there was print, TV, radio, direct mail and outdoor those were your only options but today technology runs our lives so everything is digital eventually. If digital is not part of your strategy then you would not be relevant so digital marketing is marketing in 2020.
