What is "opojaz"

OPOJAZ (OПOЯЗ) (, Obščestvo izučenija POètičeskogo JAZyka, "Society for the Study of Poetic Language") was a prominent group of linguists and literary critics in St. Petersburg founded in 1916 and dissolved by the early 1930s. The group included Viktor Shklovsky, Boris Eikhenbaum, Osip Brik, and Yury Tynianov. Along with the Moscow linguistic circle it was responsible for the development of Russian formalism and literary semiotics. It was dissolved under political pressure as "formalism" came to be a political term of opprobrium in the Soviet state.
