2) There’s controversy around who actually invented emojis:

While the Egyptians are responsible for creating hieroglyphics (which could be argued as the first true emoji), Japanese phone carrier Docomo has most often been widely credited as the originator of what we know as emoji today. However, new evidence shows that, in fact, Softbank Japan released a phone with support for 90 distinct emoji characters in 1997 which is 2 years before Docomo released emoji capability on their phone.
