In 1991, Egmont purchased the Fleetway arm of IPC Media in the UK from a company owned by Robert Maxwell, and merged it with their existing comics publishing division, London Editions, and thus became Britain's largest comic book publisher. The resultant company, Fleetway Editions, was absorbed into the main Egmont brand by 2000, having largely divested itself of its original portfolio (such as "2000 AD") and continued with only reprint and licensed material titles (e.g. "Sonic The Comic"). The Fleetway archive comprises those comics characters first published by IPC subsidiaries on or after 1 January 1970, together with 26 specifically named characters first published in Buster before that date. In August 2016, The IPC/Fleetway library was sold to Rebellion Developments, who had previously acquired 2000 AD.
