What could "Ab" mean...
Wikipedia said:Aktiebolag (literally "share company" or "stock company") is the Swedish term for "limited company" or "corporation".
When used in company names, it is abbreviated "AB" or "Ab" (roughly equivalent to the abbreviations Ltd and PLC).
It's probably something related to AB Testing, where you have multiple UI's for the same website to try and gather statistics...
If they're not using Google analytics they're probably going to redirect users within these domains on their tests.
I still find it ridiculous that they named it the Xbox One
how are we supposed to distinguish it from the original Xbox (which, presumably, should be called XBOX1)
I guess they've just made it 100% obsolete :3
