By greatest invention I mean something that had big and positive influence.
The smartphone
That was 20th century.
Didn’t the iPhone come 2007?
Sure, but the iPhone was far from the first smartphone.
Okay, the iPhone and the smartphones after it. Better? :)
Honestly the iphone was the first big (culturally) smartphone it not the first one.
I totally agree. But the question was about inventions not mass adaption.
That’s like saying Henry Ford invented the car because the Model T was the first widely available one.
I think anything you could call a smartphone had to be from post-2000 though, right?
That’s going to be a tough one to call. Nokia Communicator had diary (calendar), web browsing and email features in the 90s. You could also tether off it, but it was dialup and most phones could do that.
That was pretty much the definition of a smart phone at the time.
It may depend on your culture, but Blackberry and Windows Mobile phones were both fairly common in business circles years before iPhones.
The iPhone was an incremental advancement, not a major invention out of nowhere. The first iPhone was actually pretty crap compared to some models on the market. It wasn’t until the 3G model that iPhones took off.
What smartphones existed in the 20th century?
The IBM Simon, Nokia Communicator or Ericsson R380 for example.
