The New York Times and Los Angeles Times announced an agreement in which the Los Angeles Times will distribute The New York Times to home-delivery customers in Southern California.

The distribution deal took effect on March 10.

“We are pleased to partner with the Los Angeles Times to deliver The New York Times to more readers in Southern California,” said Scott Heekin-Canedy, senior vice president of circulation for The New York Times. “This arrangement will open up dozens of new areas and hundreds of thousands of new homes for home-delivery of our newspaper.”

Under the terms of the agreement, The Times will switch its San Diego County home delivery to the Los Angeles Times. The Times’ larger home-delivery reach in San Diego County will allow The New York Times to become available in 21 additional ZIP codes for a total of 84 ZIP codes throughout the county.

As of March 24, the Los Angeles Times is responsible for home delivery of The Times to most of Los Angeles, including Malibu, Santa Monica, Beverly Hills and Hollywood.

The distribution agreement will allow The New York Times to expand into another 26 Los Angeles ZIP codes for a total of 89 there. At the same time, the new agreement will allow The New York Times to expand into 11 Ventura County ZIP codes, including Ventura and Oxnard.

The Los Angeles Times has been the home-delivery provider for The New York Times in Riverside County since July 1999 and in Santa Barbara since July 2001.
