In 1965, Wolfe published a collection of his articles in this style, "The Kandy-Kolored Tangerine-Flake Streamline Baby", adding to his notability. He published a second collection of articles, "The Pump House Gang", in 1968. Wolfe wrote on popular culture, architecture, politics, and other topics that underscored, among other things, how American life in the 1960s had been transformed by post-WWII economic prosperity. His defining work from this era is "The Electric Kool-Aid Acid Test" (published the same day as "The Pump House Gang" in 1968), which for many epitomized the 1960s. Although a conservative in many ways (in 2008, he claimed never to have used LSD and to have tried marijuana only once). Wolfe became one of the notable figures of the decade.
