The Paywall Empire: How RELX Turned Information Into a Fortress

RELX began as two very different creatures. On one side, Reed International—a British trade publisher with roots in newsprint and industrial journals. On the other, Elsevier—a Dutch scientific publisher founded in 1880, named after a 16th-century family of printers. Their 1993 merger created a publishing juggernaut, but the real transformation was still to come.

As the web upended print, most publishers panicked. RELX didn’t. It pivoted hard—early and aggressively—into digital subscriptions, analytics, and proprietary databases. By the 2000s, RELX had moved beyond content to control the infrastructure around it.

Its crown jewel: Elsevier , which today publishes over 2,800 scientific journals, including The Lancet and Cell . But what really matters isn’t the journals—it’s the paywalls . University libraries and researchers pay steep annual fees to access Elsevier’s ScienceDirect platform. For decades, Elsevier operated what critics called a “double-dip” model: charging authors to publish and institutions to read.

But RELX is bigger than academic journals. It quietly built three other massive business units:

Each business shares a common model: own the data, lock in the customer, and layer on analytics. Today, RELX is less a publisher and more a B2B data monopoly. It powers courtrooms, labs, police departments, and insurance claims desks—often invisibly.

The company generates over £9B in annual revenue, with recurring subscriptions making up the vast majority. It’s headquartered in London, but its DNA is global. And while it faces growing pressure from open-access advocates and privacy critics, its moat is wide, and its margins are strong.

RELX isn’t flashy. But it’s one of the most quietly powerful information empires on Earth. If data is the new oil, RELX is the pipeline—and it charges by the drop.
