Los Angeles

Los Angeles, often initialised as LA, was a major city in California. A significant portion of LA was the neighbourhood of Hollywood, famed as a global hub for film production. However, other parts of Los Angeles were of occasional interest to the Doctor and his friends, as well as Torchwood.

20th century
The Second Doctor once took Zoe Heriot and Jamie McCrimmon to downtown LA in an effort to make them understand no society, even the most egalitarian-minded ones, could escape the difficulties of poverty. Arriving on a Christmas Eve in the late 20th century, the trio worked at the Midnight Mission and stopped a desperate homeless man from robbing the charity. (ST: Goodwill Toward Men) On another occasion, the Second Doctor, Jamie and Victoria found themselves imprisoned in the city by a tattoo artist somehow able to strip them of their faces and his minion, a former junkie trying to get her life back on track. (ST: Face-Painter) In the waning months of the 20th century, Los Angeles was home to a shady conglomerate known as InterCom, which aroused the suspicion of UNIT, after it was linked to illegal sales of plutonium. The Brigadier was joined in his investigations in the city by the fifth Doctor, Tegan and Turlough. (PDA: The King of Terror)

21st century
After Miracle Day, a renewed Torchwood team moved to Venice Beach to investigate closely what PhiCorp was up to in LA. Rex Matheson had family in this city. (TW: Escape to LA) Later, Oswald Danes presented the Miracle Rally, greatly raising his public image. (TW: The Categories of Life)
