The same text can be written in different ways. If you plan to use a certain text in multiple areas, you need not change the text to make it look new or unique, just change the font.
If a company wants to give its printed advertisement a fresh look, they need not change the tag line or their message. They can use different colors and fonts, and it will be a whole new advertisement, which will attract fresh attention. Very few will realize it is in fact the same thing in a different font. This is the power of typography in today’s technologically advanced world.
