Two-time Emmy Award–winning Energy Communications Corp. on Chula Vista's Third Avenue is the exclusive U.S. sales representative for Televisa Californias, selling advertising airtime across five Spanish-language television stations including XEWT Channel 12 San Diego/Tijuana. The agency's broadcast-ad inventory reaches more than 38 percent of San Diego County's population through XEWT's 200-kilowatt transmitter on Mount San Antonio, placing spots for South Bay businesses including Joe Finch - State Farm Insurance Agent during primetime and morning-news blocks. Latina- and women-owned since its founding over three decades ago, Energy Communications manages advertising across XEWT Channel 12, XHUAA Channel 57, and sister stations in Ensenada, Mexicali, and Imperial Valley. That cross-border footprint puts home-service and trade advertisers—including HVAC contractors at All Aire Heating & Cooling—in front of the 45.5 million annual border crossings that define the San Diego–Tijuana mega-region. Full-service campaigns combine 15- and 30-second spot production, telenovela-adjacency scheduling, and morning-show interview segments broadcast live from XEWT's Seaport Village studio—the only all-Spanish broadcast facility in downtown San Diego.
