Bernard Stiegler has written on "the homogenization of perceptual experience within contemporary culture"
Stiegler is interested in "movies, television programs, popular music, and [short videos]" and he "cites the advent of widespread internet use in the mid 1900s as decisive turning point (his key date is 1992)"
He is concerned about a "mass synchronization" and "the standardization of experience"
I wasn't totally convinced by this--in my analysis, the opposite is occurring--and Crary seems to agree. On 53 he writes: "against [Stiegler's] idea of the industrial homogenization of consciousness and its flows, one can counterpose the parcellization and fragmentation of shared zones of experience into fabricated microworlds of affects and symbols"
