The very fact that the first device you turn to, to book a movie ticket, a doctor’s appointment, a cab ride to a conference, or to check your work mail, is your mobile, and not your desktop, should indicate the usefulness and ubiquity of this platform. As of January 2018, the number of unique mobile users, globally, amounted to 3.7 billion. An eCommerce giant like Amazon spends two-thirds of its advertising budget targeting mobile users. 92% of Facebook’s revenue comes from mobile sources. This is why smart marketers are making use of mobile responsive design regularly in their business campaigns.
