This is the conclusion to a mini-series on emoji. If you haven't already heard parts 1️⃣, 2️⃣ and 3️⃣, go listen to those first.

Emoji put a once obscure group of nerds, known as the Unicode Consortium, into the spotlight. How have these cute little pictures challenged and changed this stodgy organization?

You can learn more about making your own emoji with Jenny's project, Emojination. And you can adopt an emoji of your very own through Unicode's Adopt-a-Character program.
