You are also "on the air" if you do radio. You're also "on the air" with television. Ergo, you're "on" both radio and television. This is better than saying you are "in the air" because that brings all sorts of odd images to mind. You can be "in" Mr. Ed, for example, while it's on the air, so with television (and radio plays) you're both "on" and "in" at the same time.

It's like being "on" stage "in" Hamlet.
