Adoption of New Technology since 1900

Great stuff

It would be interesting to see technologies that died, like trash compactors on the graph.

Also, any idea what’s next? PVR. iPhone. HDTV. …?

@Martin (who asked about penetration of electricity and radio): 1934 to 1947 was wartime, so I guess a lot of people used portable radios then. I checked the census (census.gov): In 1947 the US had around 39.000 households, so 3% were about 1,200 households who used radios, but didn’t have electricity yet. Quite realistic, don’t you think?

An early radio used no power at all. On the 200KHz long wave band a 10 meter aerial 200 KM from a 1MW transmitter can drive headphones just from the aerial energy. Now we can buy am FM radio that winds up with clock work.

This is super.

What is the source of Nicholas Felton’s technology adoption data?
Thanks!

Patty, I am happy to have my worked used in the classroom. Just be aware that not all the graphs on my site were created by me. Also you can subscribe to my site by Email.

No, not at all. There were about 131 million people living in the United States in 1940.
