Either during the counterculture era or from the earlier Vedanta Society. By 2000, Hinduism is the second or third largest organized religion in the USA, comparable in size to Judaism, and a large share of its believers are converts from outside the Asian diaspora.

1910s-1930s: Mainly in architecture with the explosion in period and historical revival styles. Arguably this began in the late 19th century with the English Arts & Crafts movement, but it peaked internationally in the 1910s through 1930s. In North America this was heavily driven by returning veterans from the Great War who were fascinated with traditional European architecture styles, while in many European countries there was a period of national romanticism that included references to older styles. Throw in the rise of the movies and you get a ton of interest in Old Europe and beyond. Increased exposure to non-Western cultures also led to Mayan, Egyptian, and even Chinese-inspired buildings such as the 1926 Chinese Theatre in Hollywood. This revival did coexist with, and was largely supplanted by, the emerging modern movement, although well into the 1940s and 1950s you'll find homes in the US, Canada, and UK that draw on Georgian/Colonial or exotic continental European influences (the homes of [Jean Valjean Vandruff](https://thecinderellahome.com/) are a direct continuation of the 1920s Storybook Tudor craze).

1950s-1960s: This one was more widespread, and a lot of it came from the increasing positive image of non-Western cultures and minorities in the Americas. WWII forced the West to come to terms with the negative impact of ultranationalism and chauvinism and removed a lot of the stigma associated with them, while also leaving memories of positive cooperation between Afro-Caribbean/Asian/Polynesian peoples and White American or European troops. Continuing influence of the American folk revival and dixieland jazz revival, which took root in Britain as traveling bluesmen and local skiffle and trad jazz bands, as well as Asian-Pacific and African diaspora-influenced exotica records thrived among veterans and postwar youths. This would only accelerate in the late 1950s and into the 1960s with the psychedelic and hippie subculture. While it wasn't really "nostalgia" in the sense of connecting with the post of one's own culture, the hippies and before them the exotica pioneers were more interested in the traditional culture of non-Western countries. The Beatles and Beach Boys were less interested in the era of Bollywood, package tourism, and high-rises along Waikiki, and more interested in the grass skirts and leis of Native Hawaiian costume and the classical sitar of Ravi Shankar.

2010s-2020s: Obviously a lot of people are talking about the demand side of nostalgia (capitalism run amok and despair in the future to continue to improve living conditions), but the supply side of the Internet and streaming is absolutely massive. It's just as easy to watch or listen to a major hit song or movie from 1959 as it is to get ahold of one from a couple years ago that's fallen off the charts. There are also some unpleasant reasons for all the nostalgic media (it's seen as "safer" than trying to come up with new IP for movies, or at least it was until the 2023-present rash of flopbusters), but I do think it can be seen as at least part an increased access situation similar to that of the 1920s and 1960s.
