I'd say it's a tossup between the automobile and the internet. The revolver and railroads are somewhere up there too. ------------ Railroads are not the "invention", but the "steam engine" greatly affected the historic development of US industry and commerce. "Electric lighting" would rank highly as well. Internal combustion engines and computers are the modern equivalents. The telegraph, telephone, and the skyscraper all had their impacts. (There are millions of people around the world who have no day-to-day experience with any of these inventions.)
Fire, no.
The wheel, no.
The automobile, nope.
Elevators, uh uh.
Fast food! Not even close.
Unarguably the invention that has changed the life of every American is the cell phone.
The cell phone has put us in touch with everyone. We can talk to people we hardly know, and people we hardly care for, and we can do it from anywhere. Well, anywhere that you "can hear me now."
Thirty years ago, if you wanted to talk to someone on the telephone, you either did so from your home landline, or from one of the many pay phones at the side of the road and at every gas station, convenience store, or every other conceivable business. Now you simply reach into your pocket and pull out this magic communications device. And, it isn't limited to telephone calls anymore. As a matter of fact, the majority of American youth who carry a cell phone, use it for texting, photos, or internet access, games, and 500,000 other applications. The telephone function now is secondary or tertiary at best. Many people have become so dependent upon their phones, they would find it difficult to function without it, or the two or three others clipped to their belts.
We talk and text in restuarants, during movies, some even during sex. We call from the board room, the bathroom, and the battlefield. We film and photograph with them births and deaths, friends and fights, good samartians and criminal. Yes, America would not be the nation it is today without the invention of the cell phone. It's sometimes hard to believe how far we have come with these indiscriminant little devices. A scant twenty years ago these omnipresent companions were nearly the size of a shoe box and looked more like an electric knife sharpener. Now they are so small, it is amazing they have not become more discreet. They are anything but discreet.
No more do we have to question the sanity of the person wandering down a public street talking loudly and gesturing wildly. They are not psychotic, no! They're blue toothing.
Onward and upward, I say. Viva la cell phone! What would we do without it?
Wait, I've gotta take this call.
The automobile, the modern refrigeration, airplane, tv's and more.
They made life easier, more productive, and more profitable.
Possibly the light bulb or maybe the trampoline.
The light bulb IS the most important invention in history. If it wasn't for it, we would still be watching TV by candle light!!

It had a big impact on society. It helps us keep many things together/closed.
One of the most life changing invention is the internet, It provides us with information in an instant.
The greatest impact of US expansion to the West was not a new invention. What was new was a vast network of railway extensions including the 1869 completion of the Transcontinental Railway. The US railway network allowed for faster and safer travel to the West. Settlers wishing to take advantage of the Federal Government's land policies gave citizens a chance to start a new life in the West. Travel now was not limited to wagon trains which were slow and dangerous adventures.
