Though TV had already been experimented with before this point, 1941 stands out as the year when commercial TV—including CBS and NBC—was first broadcast in the U.S. (Trivia alert: the world's first official commercial was for Bulova watches. Check it out here.)
The start of postmodernism is hard to pin down, and it's not like postmodernism is big on pinning things down anyway…but when folks do try to narrow it down, they most often list the end of WWII as the time when modernism came to an end and postmodernism put its name on the map.

Described as "a custom-crafted study of paranoia, a spew from the 1960s and—in all its hysteria, insolence, insult and rot—a desperate and important book" (source), this gonzo journalism classic had its finger on the pulse of society and remains a classic slice of American literature.
