I have also seen this tag represented as <WOBR>. I have not seen it used as such anywhere.

The WBR element stands for Word BReak. This is for the very rare case when you have a NOBR section and you know exactly where you want it to break. Also, any time you want to give the Netscape Navigator help by telling it where a word is allowed to be broken. The WBR element does not force a line break (BR does that) it simply lets the Netscape Navigator know where a line break is allowed to be inserted if needed.

Or..., according to Microsoft,
<nobr>This line of text will not break, no matter how narrow the window gets. <wbr>This one, however </wbr>, will</nobr>
