Hell, past the 40s, it wasn't much less popular. The middle of the 20th century was a fucking wild time. It was like we realized we had all this cool shit like rockets, radioactive elements, PCBs, fission, fusion, asbestos, perchlorates, plastics, CFCs, DDT, you name it, and it was like a race to find as many uses for each of them as imaginable so we could cram them into every possible aspect of modern life before anyone realized they were capable of killing us all, either individually or all at once, often in combination. The friendly atom! Better living through chemistry! Wait, shit, oops
