Among the names considered for the new console were a number of acronyms, including "Windows Entertainment Project" (WEP), "Microsoft Total Gaming" (MTG), "Microsoft Interactive Network Device" (MIND), and "Microsoft Interactive Center" (MIC).[35][36] Also among the names considered was "DirectX Box", referring to the system's reliance on Direct X. At one point, Hase jokingly came up with the names "XXX-Box" and "DirectXXX-Box" as a nod to the system's higher volume of adult content compared to Sony or Nintendo's consoles.[37] "DirectX Box" was quickly shortened to "Xbox" through an e-mail conversation, and was ultimately favored by the development team, though a number of spelling variants were tossed around, such as xBox, XboX, and X-box.[35][37] Microsoft's marketing department did not like this name, suggesting "11-X" or "Eleven-X" as alternatives.[35] During focus testing, the company put the name "Xbox" on the list of possible names simply to prove how unpopular the Xbox name would be with consumers. However, "Xbox" proved to be the more popular name on the list and was thus selected as the official name of the product.[38]
