LOS ANGELES (AP) — Google is expanding its presence in Los Angeles with the $120 million purchase of a dozen acres of vacant land in the Playa Vista area on the city's west side. Google also rents a 41,000-square-foot video production facility for subsidiary YouTube in a renovated former Hughes building in Playa Vista. Google already has bought or rented about 6.2 million square feet of space this year in the San Francisco Bay Area, bringing its total there to 15 million square feet, according to real estate brokerage statistics cited by the Times.
