Theory proposed by the British artist JOHN LATHAM which stresses the importance of process over product: structures in events (through time) are more valid than structure in art objects (in space).
In 1967 Latham's ideas were adopted by THEO BOTSCHIVER, JEFFREY SHAW and SEAN WELLESLEY-MILLER who formed the Event-structure Research Group (ERG) in Amsterdam. They proposed an alternative to 'museum art' by staging public events, encouraging physical participation, 'operational art' and 'art of real consequences'.
