With appropriate caveats and rough dating, here’s a list I can think of:
Electric lights in 1890s,
Radio communication in the mid 00’s,
Telephones in the mid 10s,
Talking Movies in the mid 20s,
Commercial Radio in the mid 30s,
Vinyl records in the mid 40s,
TVs in the mid 50s,
Computers in the mid 60s,
The microchip/integrated circuit in the mid 70s,
The GUI in the mid 80s,
Internet/Web in the mid 90s,
Smartphone in the mid 2000s,
Streaming video/social networking in the mid 2010s,
And now AI. This is a big one.
