Sally Calypso
From Tardis Wiki, the free Doctor Who reference
Sally Calypso was a news reporter in New New York. Her traffic news reports were recorded as holograms and broadcast for the people in the Motorway. If she was ever a real person, she was presumably killed by the Bliss virus along with the rest of New New York.
The hologram was turned off by the Tenth Doctor in the opening of the Motorway in the year 5,000,000,053. (TV: Gridlock)
