Los Angeles Times suburban sections

The Los Angeles Times suburban sections or zone sections were printed between 1952 and 2001 as adjuncts to the main newspaper to cover the news of and sell advertising space in various parts of Southern California that the Times considered to be in the prime part of its circulation area. The giant Los Angeles daily had a "more aggressive zoning policy than perhaps any other newspaper" because its local market was so widespread, a writer for The New York Times opined.
