The age of the spectacle was roughly 1900-1970, the years during which there were World's Fairs that captured the world's attention. The 1964 New York World's Fair was probably the peak. The 1960s had the Apollo program, probably the biggest spectacle operation in history. "We choose to go to the moon... Not because it is easy, but because it is hard." - Kennedy.
Today, spectacle, such as it is, is on screens. Watching the CGI Marvel Overextended Universe doesn't really compare. We see some exuberance in Asia, with fantastic urban buildings. (What do we get in SF? The Salesforce Tower. Oh well.) Shenzen has a celebration going on where all the big buildings downtown are lit up with LEDs all controlled together. It's very Blade Runner.[1] The closest thing we have in the US is Elon Musk's Space-X stunts.
