Yahoo! Inc.’s Internet service and NBC Universal Inc.’s Telemundo broadcast network, both of which have significant Los Angeles operations, will merge their Spanish-language Web sites in the U.S. to better reach a growing Hispanic market, the companies announced.

The Yahoo en Espanol and Telemundo.com will combine staff and share advertising income, the newspaper said. Yahoo said the move will let advertisers more easily reach Hispanics in the United States, an estimated audience of more than 11.5 million people.

Yahoo Telemundo will include content offerings tailored to first, second and third generation Hispanics through Spanish-language, bilingual and English-language content sections.
