Over the last year, ads running across Fox’s broadcasting network, Fox News Channel, FS1, Fox Deportes and Fox Business Network delivered more than 142 billion television ad impressions, according to data cited by the media company. That represented more than 10 percent of the total television advertising market, with Fox News and Fox ranking among the top six networks by television ad reach, Fox said. Fox also said three of its networks — FS1, Fox News and Fox — ranked among the top 10 for attention or effectiveness among the top 50 networks by reach. Fox and iSpot first began working together in 2015, when Fox adopted iSpot’s real-time television ad measurement capabilities.
