Google has revealed it plans to integrate dMarc technology into the Google AdWords platform, creating a new radio ad distribution channel for its advertisers.
Media buyers who sign up to use the service can automatically include radio stations in customised networks they create online.
Tim Armstrong, vice-president of advertising sales at Google, said: "Google is committed to exploring new ways to extend targeted, measurable advertising to other forms of media.
"We anticipate that this acquisition will bring new ad dollars and accountability to radio by combining Google's expansive network of advertisers with dMarc's talented team and innovative radio advertising technology.
"We look forward to working together to continue to grow and improve the ecosystem of the radio industry."
