Origin

The character 媒 combines the radical for "woman" on the left with a sound component on the right that hints at the pronunciation. Historically, in many cultures including China and Japan, women often played the role of matchmakers or go-betweens who arranged marriages and mediated between families. The "woman" element captures this cultural association with the job of intermediary, while the right side provides a phonetic clue to how the character should be pronounced. Over time, the meaning broadened beyond just matchmakers to include any kind of mediator or intermediary.
