That may be true but do you think that some people who are operating an offline business will mostly focus to advertise digitally with the use of internet ? I could understand the use of radio because that is much more popular these days.We are living in a kind of era where many businesses are being advertised online. The fact of the matter is that digital marketing is being used in almost every aspect. I think that digital marketing will become more advanced and it shall be used even more s well.
