Its largest metro areas are Los Angeles-Long Beach-Anaheim, CA, Riverside-San Bernardino-Ontario, CA and San Francisco-Oakland-Fremont, CA (Census V2025 metro estimates), and 5.8% of residents lived in rural areas at the 2020 Census (Census 2020).
Place-based media meets California residents where they already are: at the pump, in line at the pharmacy, in the clinic waiting room, on campus and at the grocery store. Every venue type in our network is available across California, and one managed plan covers creative specs, placement, photo proof and AAM-audited reporting.
