That’s not nearly on the same level. The first commercially successful cell phone was the dynatac 8000, a phone made by an American and in the American market

What are world-changing creations made by a country other than the US?

Almost all the global society-altering creations i can think of FROM THE PAST 100 YEARS are from America. I highly doubt that’s true, so I’m looking for counter-examples.

To clarify, I’m looking for items on the level of:

• the internet
• rock music
• nuclear weapons
• ai
• airplane flight (older than 100 years)

And clearly I’m not just including things that improved the world.

The best ones i can think of are (I think):

• Rocketry (Germany)?
• Cheap tech manufacturing (Asian countries)?

EDIT:

Actually rocketry has been around much longer than 100 years. Even the category of “modern rocketry” begins in the late 1800s. Source: www.grc.nasa.gov/www/…/history_of_rockets.html

EDIT 2:

A further explanation of what level I’m talking about.

There has to be a clear before and after, and it has to directly and quickly effect most of the world. For example the Internet. There’s life before the internet, and there’s life after the internet, which are both very different.

As opposed to for example if someone makes a groundbreaking foundational research discovery that effects the entire realm of their field of study, but doesn’t quickly and directly create a difference in most people’s lives, then it doesn’t fit the category.
