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?。
