History Previously known as Reed Elsevier, the company came into being in 1993 as a result of the merger of Reed International, a British trade book and magazine publisher, and Elsevier, a Netherlands-based scientific publisher. The company rebranded itself as RELX in February 2015.

Reed International In 1895, Albert E. Reed established a newsprint manufacturing operation at Tovil Mill near Maidstone, Kent. The Reed family was Methodist and encouraged good working conditions for their staff in the then-dangerous print trade.

In 1965, Reed Group, as it was then known, became a conglomerate, creating its Decorative Products Division with the purchase of Crown Paints, Polycell and Sanderson's wallpaper and DIY decorating interests.

In 1970, Reed Group merged with the International Publishing Corporation and the company name was changed to Reed International Limited. The company continued to grow by merging with other publishers, producing high-quality trade journals under IPC Business Press Ltd and women's and other consumer magazines under IPC Magazines Ltd. Reed entered the United States in 1977 by acquiring Cahners Publishing, founded by Norman Cahners.

In 1985, the company decided to rationalise its operations by focusing on publishing and selling off its other interests. Sanderson was sold to WestPoint Pepperell, Inc. of Georgia, United States, that year, while Crown Paints and Polycell were sold to Williams Holdings in 1987. The company's paper and packaging production operations were bundled together to form Reedpack and sold to the private equity firm Cinven in 1988. Reed then expanded its publishing division by acquiring Technical Publishing from Dun & Bradstreet.

Elsevier NV In 1880, Jacobus George Robbers started a publishing company called NV Uitgeversmaatschappij Elsevier (Elsevier Publishing Company NV) to publish literary classics and the encyclopedia Winkler Prins. Robbers named the company after the old Dutch printers family Elzevir, which, for example, had published the works of Erasmus in 1587. Elsevier NV was originally based in Rotterdam but moved to Amsterdam in the late 1880s.

Up to the 1930s, Elsevier remained a small family-owned publisher, with no more than ten employees. After the war it launched the weekly Elsevier magazine, which turned out to be very profitable. A rapid expansion followed. Elsevier Press Inc. started in 1951 in Houston, Texas, US, and in 1962 publishing offices were opened in London and New York. Multiple mergers in the 1970s led to name changes, settling at "Elsevier Scientific Publishers" in 1979. In 1991, two years before the merger with Reed, Elsevier acquired Pergamon Press in the UK.

Cahners Publishing Cahners Publishing, founded by Norman Cahners, was the largest U.S. publisher of trade or business magazines as of his death in 1986. Reed International acquired the company in 1977.

Significant divestments In February 1997, Reed Elsevier divested its trade publishing group (including Heinemann, Methuen, Secker & Warburg, Sinclair-Stevenson, Mandarin, Minerva and Cedar) to Random House. In 1998, Reed Elsevier sold the children's divisions of Heinemann, Methuen, Hamlyn and Mammoth to the Egmont Group.

In February 2007, the company announced its intention to sell Harcourt, its educational publishing division. On 4 May 2007 Pearson, the international education and information company, announced that it had agreed to acquire Harcourt Assessment and Harcourt Education International from Reed Elsevier for $950m in cash. In July 2007, Reed Elsevier announced its agreement to sell the remaining Harcourt Education business, including international imprint Heinemann, to Houghton Mifflin for $4 billion in cash and stock.

Between 2006 and 2019, in 65 separate deals, the company systematically sold its 300 print, business to business magazine titles, reducing the proportion of print revenues from 51% to 9%. Advertising, which had been the largest source of revenues when RELX was founded, represented just 1% of sales in 2018.

In July 2009, Reed Elsevier announced its intention to sell most of its North American trade publications, including Publishers Weekly, Broadcasting & Cable, and Multichannel News, although it planned to retain Variety. Sister publication Video Business to Variety was closed in January 2010.

In April 2010, Reed Elsevier announced that it had sold 21 US magazines to other owners in recent months, and that an additional 23 US trade magazines, including Restaurants & Institutions, Hotels, and Trade Show Week would cease publication. The closures were mostly due to the weak economy including an advertising slump. Variety, the company's last remaining North American title, was sold in October 2012.

In 2014, Reed Business Information sold BuyerZone, an online marketplace; emedia, an American provider of research for IT buyers and vendors; and a majority stake in Reed Construction Data, a provider of construction data.

In 2016, RELX sold Elsevier Weekly and BeleggersBelangen in the Netherlands. In 2017, the company sold New Scientist magazine. In January 2019, RBI sold its Dutch agricultural media and selected international agricultural media portfolio (including Poultry World) to Doorakkeren BV. In August 2019, Flight International and FlightGlobal were sold to DVV Media Group. In December 2019, RBI announced plans to sell the Farmers Weekly magazine title, website and related platforms, events and awards to MA Agriculture Limited, part of the Mark Allen Group. In May 2024, RX sold the Gamer Network to IGN Entertainment, division of Ziff Davis. However, it retained the EGX convention and Popverse.
