How Britain Learned to Say No to American Media Deals

The Department of Justice cleared Paramount's acquisition of Warner Bros Discovery in June without requiring a single concession. Three months later the UK's Competition and Markets Authority is preparing to block or reshape the same deal.

This isn't a delayed echo of American caution — it's a different judgment about what the deal actually does.

For decades, the UK CMA treated US antitrust decisions as probative. If the DOJ saw no serious competition problem, British regulators would defer, adjust their scrutiny downward, assume they were missing something.

The mechanism is simple: the US applies a consumer-welfare test to concentration that works if prices and immediate consumer choice are the relevant measures. Paramount and Warner Bros Discovery don't compete directly on price. They operate in a world of licensing, bundling, and platform power. The DOJ's framework sees no problem. The CMA is asking a different question: does this deal reduce the number of genuinely independent voices producing content for British audiences?

The UK isn't just reviewing a deal the US already approved. It's announcing that it no longer believes US regulators correctly measure what 'competition' means.

Global media companies will now develop distinct strategies for US and UK approval. The way pharmaceutical companies already do — and Britain has chosen to pay the cost of deciding for itself rather than converge toward whatever the largest economy's regulators decide is acceptable.
