User blog comment:Craiglpalmer/Wikia is now Fandom powered by Wikia/@comment-27669113-20160926183414/@comment-5831669-20160926190634

Fandom is the name for the whole brand. And we're dropping the convention to call wikis 'wikias'. So in your example it would be 'Gorillaz Wiki'. However, bare in mind that you can customise the default—just like 'Wookiepedia' did.
