According to Brandwatch's latest Emoji Report, 3.2 billion emojis are used to express joy, sorrow, anger, sadness and love, among many other emotions, each year.

The use of emojis on Twitter still corresponds to the basic idea of the Japanese inventor Shigetaka Kurita, who developed the first 176 emojis.

He designed them in 1998 to express feelings and emotions in a character, which grew in popularity and use due to the character limits of SMS which is similar to Twitter’s original 140-character limit.

Nowadays, there are an incredible 2,789 Emojis available via Unicode.

We would be doing well to figure out how to express all those 2,789 emotions ourselves.

And for the day that's in it, Twitter has released some insights into the use of emojis on the platform, including the emojis used to draw attention to large social and political movements.

These are usually limited to a certain time or location.
