The first anniversary in 1918 of the October Revolution was the occasion for the performance in Petrograd of what is generally held to be the earliest substantial post-Revolutionary satirical work, Mayakovsky's anti-religious pageant Mystery-Bouffe ("Misteriyabuff"). But such innovative epic undertakings, like the new outdoor spectacles for mass audiences, were to have little significant impact on theatrical developments during the mid-1920s period of the New Economic Policy (NEP), not least because of the financial and organisational difficulties these productions presented. Instead, smaller-scale events — such as Mayakovsky himself would also contribute to — became the real focus for satirical work during most of the 1920s.
