Abstract expressionism (ie modern art) was actually pushed by the CIA as well (source), though the motivation in this case is murkier
Was modern art a weapon of the CIA?
The Abstract Expressionists emerged from obscurity in the late 1940s to establish New York as the centre of the art world. But were they pawns of US spies in the Cold War?
I always thought Suprematism was what the Soviets were pushing, now I read the wiki article and it seems it was not, and Socialist realism was, and I guess it was the hyper-realism you talk about?
