With growing technology and laziness of human beings, it is now possible to buy literally anything online. You name it and you'll find it and have people deliver it to you. The rise of the E-commerce business combined with increase in the use of the internet, gave rise to E-marketing-Digital Marketing. Digital Marketing is basically marketing the products on the internet. This is not going out of fashion anytime soon, as its just going to grow with audience's demands. Starting your career in this field would be good as there's demand and good pay and a huge possibility of growth. All the best @Ali.
