In this rollicking tech and pop culture history, Keith Houston follows emoji from its birth in 1990s Japan, traces its Western explosion in the 2000s, and considers emoji's ever-expanding lexicon. Named for the world's most popular pictogram, Face with Tears of Joy tells the whole story of emoji for the first time.
