TARDIS Wiki (in-universe)

Tardis was a website that the human Osgood had open in another Chrome tab while settling down to watch Doctor Who on iPlayer with her Zygon counterpart. It bore the heading of "Fandom". Its logo resembled the police box exterior of its timeship namesake. (WC: The Zygon Isolation)
