ASCII ribbon campaign

The ASCII ribbon campaign was an Internet phenomenon started in 1998 advocating that email be sent only in plain text, because of inefficiencies or dangers of using HTML email. Proponents placed ASCII art in their signature blocks, meant to look like an awareness ribbon, along with a message or link to an advocacy site:
