Like modernism, postmodernism was an international phenomenon with significant regional variants. Britain played an important role in mediating between the very different postmodernisms developing in North America and Continental Europe. It helped that London was at the centre of architectural discourse in the 1970s. The Architectural Association attracted international figures such as Charles Jencks, Léon Krier, and Rem Koolhaas, while publications such as Architectural Design and Andreas Papadakis's Academy Editions imprint combined coverage of new buildings with excursions into theory and history. James Stirling, John Outram, and Edward Jones won important overseas commissions, while the work of Terry Farrell, Jeremy Dixon, and others was exhibited at the seminal 1980 Venice Biennale.
