The evolution of the digital industry is something which did not just start today, rather commenced from the 14th century itself, wherein Gutenberg came in with his printing press. A century or two after this, somewhere in the 1700s what started coming in were the advertisements that started coming in the magazines. And if we talk about the 1900s, Radio, as well as television, started coming in as the means where people could reach masses. So, by the beginning of the second half of the 20th century, Radio, Television as well as the print mediums became the hubs wherein advertisers would pay and advertise their products and services. And this series of growing technologies, directly or indirectly, knowingly or unknowingly, gave rise to a new need for cheaper means of advertising and marketing. And as necessity is the mother of all creation, here too the need of a cheaper means of advertising gave rise to the digital means of marketing and advertising, as it was not everyone's cup of tea to advertise in newspapers or on television, so this is how the internet started to come in use for digital marketing, and here we are today, living in a world, where without digital marketing, most firms can not even imagine their marketing budgets.
