The term "digital marketing" started to become widely used in the late 1990s, with the rise of the internet and the first search engines. However, the concept of using electronic channels to promote products and services has been around much longer than that. For example, in the 1980s, the Yellow Pages directories were often used as a way for businesses to advertise themselves to a wider audience. With the advent of the internet, businesses were able to reach a larger audience more easily and at a lower cost. Today, digital marketing encompasses a wide range of activities, including search engine optimization, social media marketing, email marketing, and more.
