IPC Media, based in the Blue Fin Building behind Tate Modern, is to be rebranded Time Inc. UK.
The decision has been taken by its parent company Time Inc. Its legal name will be 'Time Inc. (UK) Ltd'.
Marcus Rich, Time Inc UK CEO, said: "We are proud of what we have achieved at IPC over many years and we are excited to extend that success as a more integrated part of Time Inc."
IPC, the International Publishing Corporation, was formed in 1963 by media tycoon Cecil Harmsworth King who brought together Newnes, Odhams and Fleetway publications.
A one time IPC owned two national daily newspapers and two Sunday papers. The slightly shrunk group was bought by Time Warner in 1998.
