According to statistics; the number of smartphone users worldwide increased one billion since 2016. This is not surprising news when I think of how many of us left that still turn on our desktops or laptops often when we do not work? Especially in the last few years; most successful brands made their websites optimized for mobile use. Mobile screens got bigger than they were at the beginning of the 2000s. Now they are more user friendly for shopping, playing games and reading news.
