He will be in charge of optimising the company’s audience, rolling out its programmatic strategy and introducing advanced data-led strategies.
Bradley will also oversee a new team, which is yet to be recruited, working with CNN International's regional sales heads to develop "new digital components for integrated advertising and sponsorship solutions".
Rani Raad, the chief commercial officer at CNN International, said: "CNN Digital is flying high in terms of audience, editorial product and the solutions we've delivered clients to date.
"Rob brings to us a unique mix of analytical pure-play digital and data experience combined with a solutions-based approach to complement the bespoke campaigns we deliver to clients all over the world.
"While multi-platform sales will remain a core part of our digital commercial strategy, it is clear to me that Rob's expertise and vision can continue to evolve CNN's leadership in digital with world-class commercial solutions."
Bradley will join CNN International later this month and will report to Raad.
He said: "Using the latest technology, the new digital advertising team will advance CNNI’s integrated solutions and ability to offer truly bespoke, data-driven and impactful campaigns targeted to the right audience at scale.
"Programmatic will be part of the all-important holistic approach for today's digital media owner – with a premium-end programmatic offering from CNN attracting brands that want intelligent data-driven private marketplaces and high-impact ad units alongside standard units to gain scale."
