radio button为什么叫radio button？

一直很好奇，为什么单选框取名叫radio button，查了一下，

维基百科是这样说的:
A radio button or option button is a type of graphical user interface element that allows the user to choose only one of a predefined set of options (that's opposite to tick boxes).

They 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

原来，老式汽车收音机都是只能按下一个键，其他键会马上弹起来的，也就是说同一时刻，你只能选择一个，所以把这种现象对应到计算机可视化组件里面叫做RadioButton，这个名字还真有点意思，真佩服这个命名的家伙，不知道是谁家第一个取名叫RadioButton？微软?Borland?。
