In 2016 the original emoji character set was acquired as part of New York's Museum of Modern Art's permanent collection, a testament to their global impact.
As of 2016 there are estimated to be in the region of 2000 emoji characters but despite this huge collection, emoji development doesn't stand still.
This meant users were able to describe multiple emotions or circumstances through these icons, which could act as a linguistic short-hand to express much longer and more complicated textual messages.
At the same time mobile network operators benefited from using just a single character to send an emoji, resulting in the consumption of fewer resources.
