Radio buttons were named after the physical buttons used on older car radios to select preset stations ? when one of the buttons was pressed, other buttons would pop out, leaving the pressed button the only button in the "pushed in" position.

[edit] HTML In web forms, the HTML element <input type="radio"> is used to display a radio button.
