Even though null definite objects are usually ungrammatical in English, they are widely used in certain special registers. This paper investigates object drop in the recipe and, to a lesser extent, match broadcasting registers in English, contributing an analysis of a substantial set of naturally occuring data, hence making it possible to verify observations from previous syntactic studies of the phenomenon, which were based on a restricted array of isolated sentences. Having shown that the data support the assumption that the unrealised object is syntactically active, I propose a novel analysis of missing objects in special registers, guided by recent developments in the generative linguistic theory. Null realisation of the object is considered as an issue of externalisation and intralinguistic variation is attributed to the rules operating at the SM interface which make it possible to extend the application of copy deletion, as assumed within the copy theory of movement
