Enders Analysis has estimated that an ITV-Sky sales tie-up would hold just over 30% of the UK video ad market.
Overall, it calculated that tech giants Google, Meta and Amazon account for 55% of the total UK ad market but, narrowed down to just video, Sky Media and ITV Media would hold just over 30%, a share that would be “very likely to decline over time”.
A key test in this investigation, Enders projected, would be convincing the CMA that the relevant ad market in which ITV and Sky competes is broader than just the UK broadcasters.
It added: “It would be a missed opportunity for the CMA not to reconsider what the definition of the relevant advertising market may be, and whether some or all of advertising in other video should be included.
“National broadcasters must grow in order to compete against the global tech streamers, including YouTube.”
