Google is largest ad platform, not Facebook: Zuckerberg on competitors

During his antitrust hearing, Facebook CEO Mark Zuckerberg pointed out that in many areas, Facebook was "behind" its competitors. He said Amazon is the "fastest-growing" ads platform while Google is the "largest". "For every dollar spent on advertising in the US, less than ten cents is spent with us," Zuckerberg added. He further said that TikTok is the "fastest-growing app".
