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.
The second Doctor once took Zoe Heriot and Jamie McCrimmon to downtown LA in an effort to make them understand more about how 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.

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)
