tel•e•pixXx
From Tardis Wiki, the free Doctor Who reference
tel•e•pixXx was a social networking used in the year 2323. It was used by a group of time tourists who had attended the 1966 World Cup Final in the Dalek Dome's Dalek invasion attraction. They posted a picture at Carnaby Street in London and another in the front of the Golden Gate Bridge, San Francisco. Posts received showagains and lurveits.
When some of the Dalek Dome's simulacrum Daleks manifested in the real world and invaded Earth, people used tel•e•pixXx to plead for help and update others of the destruction. (COMIC: Liberation of the Daleks)
