CNN will shift the bulk of its operations behind its Spanish-language efforts to Mexico City, scaling back production of content for linear television in favor of work aimed at reaching a younger audience that favors mobile video.

The move is likely to mean the elimination of jobs in Miami and Atlanta, but will also result in a ramp-up of jobs in Mexico and Los Angeles, where CNN will aim to add more than staffers, according to a person familiar with the plans, which were disclosed to employees Thursday afternoon. CNN CEO Chris Licht had nodded to the future of the Spanish-language network in November at a town-hall meeting.
